Raise to 25 Minimum Age for Alcoholic Beverage and Tobacco Use in U.S.: Lower Legal BAC Max to 0.05%

The harmful effects of alcohol abuse and tobacco use are well known. A large percentage of those abusing them are young persons under age 25.

Most abusers of these products began using them before the age of 21 and certainly well before the age of 25. .

Human Brains Are Not Fully Developed Until Age 24 or 25
One reason for the poor judgment that leads to alcohol abuse among young persons is that persons’ brains are not fully developed until their mid20s. According to the Alcohol Pharmacology Education Partnership [1], “there is clear evidence that the brain does not mature fully until about age 24.”

“The rational part of a teen’s brain isn’t fully developed and won’t be until age 25 or so” according to the University of Rochester Medical Center [2].

Raising the minimum age for consuming alcoholic beverages to age 25 and raising the minimum age for tobacco use to age 25 would benefit young people enormously. This includes raising the age for using e-cigarettes to 25. Using e-cigarettes, also called vaping, is also very harmful, as noted numerous sources, including the CDC in “Quick Facts on the Risks of E-cigarettes for Kids, Teens, and Young Adults [3].”

Alcohol abuse is high among college students, who are primarily under age 25. The National Institute on Alcohol Abuse and Alcoholism [4] cites a national study as finding “almost 53 percent of full-time college students ages 18 to 22 drank alcohol in the past month and about 33 percent engaged in binge drinking during that same time frame.” .

Death, assaults, sexual assaults, and academic problems are some of the problems alcohol abuse among college students leads to according to collegedrinkingprevention.gov [5], citing studies linked to in its article.

Passing and enforcing a minimum age limit of 25 would stop a lot of college student alcohol abuse. If effectively enforced, it could also eliminate alcohol abuse by high school students as well as by high-school dropouts in their teens and early twenties.

Raising the minimum age for consuming tobacco and alcoholic beverages could do enormous good. But additional benefits can come from reducing the maximum legal blood alcohol concentration to 0.05% from the current 0.08% limit in the United States. .

Lower the Maximum Legal BAC to 0.05%
Negative effects of alcoholic beverages occur well below 0.08%, including negative impacts on driving, as reported by Michigan Medicine [6] and ePermitTest [7], as well as numerous other sources.

Many countries already have a BAC maximum limit of 0.05% or less including Canada, France, Germany, and Italy, as noted by various sources, including RUPissed.com [8] and drinkdriving.org [9].

Litter Is a Side Issue
In addition to the health risks from alcohol and tobacco use itself, one of the side problems is the litter generated by them. Studies indicate that cigarette butts are one of the most common items among litter. [10] The picture below shows cigarette butts beside a sidewalk along Virginia Avenue here in Lexington, Kentucky on September 28th, 2021.


Furthermore, empty cigarette packages and alcoholic beverage containers are high on the list of litter too. I know I often see smoldering cigarette butts on the sidewalk or ground, as well as empty cigarette packages and alcoholic beverage containers--often broken beer bottles. Smoldering cigarette butts sometimes start fires. Broken glass bottles can cut persons or tires on vehicles.

Raising the age to begin consuming such products and effectively enforcing the age limit could reduce this litter, and thus reduce the accompanying risks of fires and cuts caused by the poor judgment of individuals.

Closing Thoughts
Raising the minimum age for consuming alcoholic beverages and using tobacco to 25 might prevent persons from ever starting to consume alcoholic beverages or use tobacco products. By age 25 the more-fully-developed brains and better judgment of young persons might lead them to conclude that the risks of using such products are not worth it. I certainly hope so.

Solar Energy, Including Solar Cars, May Be the Way of the Future

I envision solar energy as the way of the future. I even expect the majority of cars to be solar-powered.

I admit that I may be dreaming. But there seems to be increasing support for solar power, which is becoming more practical.

What About Fossil Fuels?
Use of fossil fuels like coal, oil, natural gas, and gasoline is likely to decline dramatically in coming years. Indeed, their use is already declining. One reason: the pollution incurred by their production, transportation, and consumption. Another reason: their limited supply.

What About Alternatives to Fossil Fuels Other Than Solar Energy?
Solar energy is not the only alternative fuel source that can replace fossil fuels. Nuclear energy, wind power, and hydroelectric power are also in use and being considered for expanded use.

But nuclear energy is arguably much more dangerous than other fuel sources, including fossil fuels. Past accidents like the 1979 partial meltdown at Three Mile Island in Pennsylvania, the 1986 disaster at Chernobyl in Ukraine , and the 2011 Fukushima disaster in Japan that followed an earthquake are examples. The need to store radioactive nuclear waste may be an even larger problem--a huge one. The United States Nuclear Regulatory Commission states “the only way radioactive waste finally becomes harmless is through decay, which for high-level wastes can take hundreds of thousands of years.”

Wind power requires turbines that take up a lot of space and kill enormous numbers of birds. Furthermore, they only work when the wind is blowing. Some areas seldom receive significant winds.

Hydroelectric power is useful in certain areas. For example, Norway generates most of its electricity this way. But relatively few places seem to have water resources suitable for safely producing hydroelectric power in large quantities. Altering water flow for electricity generation affects the environment, droughts impact water availability, and some areas lack much water to start with.

How About Solar Energy?
The sun offers an enormous potential amount of energy that can be used for solar-power. The cost of solar panels has dropped enormously in recent years. Economies of scale can lead to further huge decreases in upcoming years. And solar power is already price-competitive with other energy sources in some areas.

A weakness of solar energy is that it doesn’t work at night when the sun isn’t shining. During times like the twilight before dawn in the photo taken the morning of September 7th, 2021 of part of the Lexington, Kentucky skyline below, solar power would not be generated. And the electric lines in the photo, like others in Lexington, are powered entirely or almost entirely by fossil fuels, which remain the #1 source of energy generation here in Kentucky.


Furthermore, on cloudy days much less energy is produced than on sunny days. But the improvement of the quality of solar panels and of the batteries that store solar energy for future use are helping to overcome this major weakness.

A bigger concern is potential climate alterations from massive use of solar power. Whether this would occur is debatable. But even if so, if solar power generation is distributed across the planet rather than concentrated in certain areas, such changes might be mitigated in my amateur opinion.

While solar power production remains a small percentage of electric power generation in the United States, it is increasing according to data from the U.S. Energy Information Administration.

What About Solar-Powered Cars?
Aptera Motors is mass producing a solar-powered car this year (2021) according to the Washington Post. I admit though that the car is a three-wheeled vehicle that only seats two persons and its travel range is relatively limited, depending on the weather. The vehicle has numerous limitations.

We are still a long way from having a solar-powered, normal-sized car that can travel long distances just on solar power. But as efficiencies of design improve, I’m confident that it will be the wave of the future at some point. But I admit I’m not an expert, just offering one opinion that may be wishful thinking. But at least I'm not the only one who sees potential.

Closing Thoughts
Solar energy definitely appears to be the best source for electricity generation for the future as it looks now. Even solar-powered autos may become feasible a few decades in the future if efficiencies of design continue advancing.

N95 Masks: Some Benefits, Risks/Weaknesses, Etc.

Persons in the general public are wearing N95 masks much more in recent months due to the COVID-19 pandemic.

Because of increased production and supply, the masks can now be purchased easily by the general public. Early in the pandemic persons were urged to not purchase them to save the limited supply for medical professionals.

Benefits
The current touted main benefit of course is protection against many particles of COVID-19. But N95 masks also help protect against transmission of the flu and many other diseases, as well as dust. N95 masks offer more protection than cloth masks. According to an OSHA webpage (1) , “When worn properly (with the mask making a tight seal with the user’s face), surgical N95 masks can filter at least 95% of very small (0.3 micron) test particles.”

Risks/Weaknesses
But there are risks and weaknesses. A study found (2) that wearing facemasks for long periods often produced “headaches, rash, acne, skin breakdown, and impaired cognition.”

For one thing, wearing the masks does make breathing more difficult. Furthermore, wearing them offers significant health risks for certain at-risk groups. For example, a study linked to on the National Institutes of Health website (3) discusses the risks to persons with COPD of wearing N95 masks.

An article in The Atlantic (4) questions whether the benefits of masking children outweigh the risks.

Furthermore, the N95 masks by definition only remove at least 95% of particles of a particular size. And the letter N in N95 indicates the masks do not protect against such things as oil. P95 masks protect against oil. No mask is 100% effective.

Wearing N95 Masks
N95 masks come in different sizes. For one to work properly, it has to be the right size for an individual’s face and needs to be put on properly. Furthermore, it’s nice to have clean hands when attaching the mask.

The OSHA website includes videos (5) about fit testing for N95 respirators. Since N95 masks made by different companies often differ in design, company websites often provide specific guidance too. For example, a Prestige Ameritech webpage (6) provides links to information about sizing and applying its ProGear® N95 respirator masks. That happens to be the type I purchased, and below is a photo of a box containing some of those masks, as well as a photo of an individual mask. But there are numerous other companies making the masks, and I am not affiliated with Prestige Ameritech in any way.

N99 and N100 Masks
In addition to N95 masks, there are N99 and N100 mask which protect respectively against 99% and 99.97% of the particles that the N95 is 95% effective against. But these masks are more expensive than N95 masks, likely harder to breathe through, and wearers likely experience side effects of wearing them that are more severe than those from wearing an N95 mask.

Cleaning and Reusing N95 Masks
While N95 masks are considered to be disposable, single-use devices, there are procedures for cleaning and reusing them. as noted in a study linked to on the National Institutes of Health website (7) .

Closing Thoughts
I’m not a medical professional and can give no medical advice. But I feel each individual needs to carefully consider the benefits and risks of wearing an N95 mask versus wearing just a cloth one or not wearing a mask.

Personally, I typically wear an N95 mask now while riding on my city’s bus system and while visiting the grocery or public library. However, at my workplace which seems to be well ventilated and where I seek to maintain social distancing, I normally still wear a cloth mask with three layers. Wearing an N95 mask for four hours or longer at work seems like a lot. I do feel the pressure on the bridge of my nose and my face from the tighter fit and a bit more difficulty breathing while wearing it. But I do feel that for me its benefits outweigh its risks when social distancing isn’t easy.

Make U.S. Mass Transit Much Better

Large numbers of low-income persons in the United States devote much of their money toward paying for personal automobiles, which they seem to consider virtually a necessity.

Automobiles are a big chunk of the budget for typical middle-class individuals too.

A key reason is that United States mass transit pales in comparison to that of many other developed nations. It seems sad that many poor persons own cars. Often persons consider them a necessity to get to and from work, buy groceries, etc.

Low-Income Persons Buying and Driving Unsafe, Undependable Cars
Frequently persons with relatively limited income buy and drive vehicles with defective brakes and other problems that make them unsafe and undependable. These persons endanger the safety of themselves and others. Furthermore, they spend money they might better use for other things like food, rent, healthcare, etc., on cars. These folks need alternatives.

Cities and Towns
A much-improved mass transit system would enable the majority of car owners in cities and towns to either do away with their cars or to drive them much less.

Subways, buses, passenger trains, and even ships on waterways are alternatives or potential alternatives to driving automobiles that typically carry only one or a few people.

Walking and bicycling is good exercise and can work for many short trips.

Carpooling with relatives or friends is another alternative. Furthermore, occasionally taking a taxicab, Uber, or Lyft is cheaper than owning a car fulltime.

Also, some employers (especially temp agencies) even provide transportation for employees to and from work. But I think riding on mass transit with an experienced, professionally trained driver is better, other things being equal.

In addition to employers offering transportation for employees, some organizations often provide transportation to and from medical appointments, etc.

Improving mass transit such as subways and buses in large cities is important. In the United States, New York City is probably the only major city where mass transit dominates over cars convincingly.

Lexington, Kentucky where I live is a city of over 300,000 people. It is blessed with a reasonably good bus system by U.S. standards. The bus system is called Lextran, and pictures below show a few Lextran buses and the Lexington Transit Center hub.
But in order to get the vast number of persons in my city who drive cars to switch to buses, my city's bus service might need to run much more frequently and to many more areas.

Improving bus service in smaller cities and towns than Lexington is important too. These smaller areas currently often have limited or no mass transit.

The first two photos show one of Lextran's buses. The last photo shows a few of the city's buses at the Lextran hub which is located downtown.
City bus systems like Lextran with their fleets of buses are leaders in the switch from diesel and gasoline to alternatives. Though the majority of Lextran buses may still be diesel powered, my city's buses include some diesel-electric hybrid ones, some powered by compressed natural gas, and some electric buses that charge at charging stations.

Dependable, frequent bus service is a key to winning over car drivers to riding buses. Providing local buses that travel the streets of cities and smaller communities frequently, accompanied by intercity buses to get to large cities, can alleviate the need for personal cars for many.

Traveling may not be needed at all for many purchases. Ordering online from Amazon, Walmart, etc., is an alternative. Also, many businesses, including some groceries and restaurants, offer deliveries via third parties such as Instacart.®

Servicing Rural Areas
Mass transit may not be economical in rural areas. But rural residents can receive many deliveries via USPS, UPS, and other delivery services that pick up and deliver groceries, etc., to homes.

Furthermore, rural residents can use alternative methods of transportation to get to towns where mass transit exists. For example, expanded availability of taxicabs, Uber, and Lyft may make it possible for even persons in relatively isolated areas to ditch their cars.

Rural residents can also carpool or ride with a neighbor or relative to the nearest town for shopping. Furthermore, after they get a ride to a town, in that town they can make a connection for a local bus or an intercity bus to go elsewhere.

Persons far away from their nearest town, nearest relative, or nearest neighbor may face the toughest time. For these persons a personal vehicle may almost be a necessity. But these individuals constitute a relatively small portion of the population. Most United States residents live in or near a town or city.

Pollution
Using mass transit can greatly reduce pollution. Enormous pollution is caused by automobiles despite efforts to improve gas mileage efficiency and the elimination of leaded gas.

More pollution is caused by the production, transportation, and use of the materials in the building of automobiles.

Electric-powered cars with batteries that are charged from the electric grid may overwhelm an electric grid that is already strained in many areas. Additionally, the charging of these vehicles often consumes electricity that is generated from fossil fuels that pollute.

Personal vehicles may become more environmentally friendly over the long term. For example, solar-powered electric vehicles that need no charging from the electric grid may become economically feasible. But that time appears to be far off. In the short term, person autos are likely to be polluting the environment in one way or another.

The least polluting forms of travel may be walking and bicycling. They provide exercise and are a great alternative to motorized vehicles for short trips. But in inclement weather such travel is tough, and transporting a family or large purchases isn’t reasonable while bicycling or walking.

Time and Space
Using mass transit can save time and space in addition to saving money. The average commuter devotes much time to driving in traffic on congested streets and highways or on long drives in less congested areas.

Furthermore, a lot of space is used to park these automobiles in home driveways, garages, and parking lots for workplaces, shopping centers, airports, etc. Much money is expended on the purchases, construction, and maintenance of these parking areas too.

By contrast, while riding a bus, subway, Amtrak train, taxicab, Uber, Lyft, or riding with coworkers, friends, or neighbors, one can talk to fellow passengers, read, enjoy the scenery, write, or listen to or watch something on your cell phone using headphones. That seems more fun than driving and dealing with traffic, parking, etc.

Savings on Highway Construction
Enormous sums of money are spent on expanding highways to accommodate increasing numbers of vehicles. If more persons use mass transit, it will reduce the need for highway expansion. This savings can pay for part of the cost of expanding mass transit. The cost of highway construction and maintenance varies widely depending on numerous factors, but it may cost millions of dollars per mile to build a new highway or widen an existing one.

Paying for Expanded Mass Transit
As mentioned in the last paragraph, the reduced expenditures on highway construction and expansion can pay for a significant part of the cost of mass transit.

Raising taxes on gasoline and diesel fuel is another way to help pay for such mass transit. U.S. taxes on such fuels are much lower than in many other countries.

As the trend toward purchasing private electric vehicles accelerates, a tax on the purchase of the vehicles and perhaps a tax on electricity could help subsidize mass transit while discouraging the purchase and driving of private vehicles.

These taxes are a way to help compensate for the environmental damage caused by private vehicles in addition to paying for mass transit.

Me in My Early College Years and My Grandparents for a Lifetime Doing Without Driving a Car
Mass transit used to be much more widespread in the United States.

My grandparents lived in relatively small towns all their lives. But as far as I know neither my maternal nor paternal grandparents ever drove a car. They depended on buses, passenger trains, walking, riding with friends or relatives, deliveries of goods to their homes by businesses, etc.

Furthermore, I remember while in college some decades ago that I rode a Greyhound bus from Lexington to a small town in southeastern Kentucky, then my parents picked me up there and drove me the remaining 30-40 miles to the family home in Jenkins. Years before that Greyhound even served Jenkins.

It’s been years now since Greyhound cancelled all service to southeastern Kentucky. But I support reinstating it, as well as service to many other areas. Additionally, with expansions to Uber and Lyft, it could be feasible to get to and from most places in the country without owning a car.

Dealing With Some Other Disadvantages of Mass Transit
Some persons fear the transmission of COVID-19 or other diseases while riding mass transit. But Greyhound, Amtrak, and commercial jets all apparently have ventilation systems that replace the onboard air every five minutes or less. Persons can wear a facemask for extra protection, indeed facemasks are currently required for travel on such transit in the United States.

Another problem is emergency travel when mass transit is not operating. If a person needs to travel to a hospital or evacuate at say 3 a.m. when mass transit is likely not operating in most areas, that is a difficulty. However, very few such emergencies occur. Furthermore, in cases of mass evacuation traffic jams, gas stations without fuel, damaged roads, etc., likely make automobile use unsatisfactory unless you leave in advance. And if you leave in advance, mass transit may be available.

Closing Thoughts
I confess that I lack the expertise to discern how cost effective and feasible it is to design and implement a quality mass transit system in the United States.

But it seems a terrible waste the way persons in the United States devote so much time, money, and materials to a transportation system that pollutes the environment so much.

We might be happier, healthier, and enjoy more free time if we devoted less time and money to purchasing, driving, and maintaining personal automobiles that sit idle for perhaps 150 or 155 of the 168 hours in a week.

I support improving mass transit. How about you?
