Update to Want To Live Longer, Read Post

My August 29, 2017 post  Want To Live Longer, Read, explained that based on a study done by the Yale School of Public Health, simply reading a book every day can prolong your life by up to two years. The current edition of the Costco Connection sent to Costco customers repeats some of that same information.at page 68.

Want to Live Longer? Read!

Do you want to live longer? Of course you do. Who doesn't? I'm going to surprise you with an easy and effective way to increase your life span. And this method requires no special exercise equipment, no gym membership and not even any special diet. The only thing you need is a book!

Yes, you read that right---a book can be your key to both a longer and more fulfilling life.

In a 2016 study published by the Yale School of Public Health, it was reported that people over the age of 50 who read any type of book for as little as 30 minutes a day could increase their lifespan on average by two  years.  The study was based on some 12 years of data originally compiled by the University of Michigan's Health and Retirement Study.

It should be emphasized that while  reading any type of book is effective, simply reading magazines and newspapers does not appear to have the same effect. Although researchers are not sure why that is the case, one theory is that reading a book causes you to think critically and make more brain connections that can protect against cognitive decline.  They referred to this effect as "deep reading."

So, if you want to live longer, get out your library card and head to your nearest library.

Will Eating Less Let Boomers Live Longer?

Will eating less let boomers live longer?  Apparently the answer to that question, unfortunately, is "No." In a recent study conducted by the National Institute of Aging and reported in the journal Nature, August 23, 2012, it was determined that large calorie restrictions by humans will not prolong your life despite the fact that other studies in monkeys and rats have shown just that effect. Those studies convinced some people that the fountain of youth lay in eating significantly less than most people need to function.

So, what type of restrictions are we talking about?  Well, the average adult human consumes about 2200 calories a day.  The believers in extreme calorie restrictions have cut their calorie intake by as much as 30 to 40 percent.  Earlier studies in mammals and other animals suggested an increase in lifespan by as much as an astounding 50% as a result of such restrictions.  While there is no question that many people consume too many calories which may shorten their lifespan, it appears eating too few calories will not necessarily have the opposite effect.

While the Nature article is certainly intriguing for its conclusions, it is unlikely that it will end the debate over calorie restrictions. As with anything else, people will continue to believe what they want to believe.  If they feel better eating less, I am sure people will continue doing so.  As  for me, I think moderation in caloric intake, as well as most other things, is still the key to good health and longevity. On the other hand, I am reminded of the statement once made by Edwin Land, the inventor of the Polaroid camera, "Anything worth doing, is worth doing to excess."
