I missed this post the last time it was up.
State of mind? Well partly. Stress can age you more then smoking can.
There is a twin study on aging that found ~22% of aging is genetic, and the rest is environmental. So we do have some control over that aging process.
The state of mind is a good place to start, but there are other factors involved. And aging is best attacked on multiple fronts.
Being mentally and physically healthy is really what the battle is all about. Aging is simply the reverse of that.
It should be pointed out that while exercise is good, apparently there is a limit. It will slow the aging process up to a point, and then change course, and then speed it up. I believe the difference is in people who are exercising for health, and athletes who really cause damage to their bodies. Football players have notoriously short lifespans.
We also need to fight oxidation, and glycation.
Calorie restriction has been shown to turn on genes related to aging, and studies (at least in rats) have been able to stimulate those genes in 4 weeks. So regular intervals of short term calorie restriction might be a good idea, instead of the torturous lifetime form only few can adhere to.
What is most important are telomeres. The short pieces of DNA at the end of chromosomes that shrink every time your cell divides. It is your bodies clock, telling you how old you are. You can do stuff to slow it, or speed it up, but nothing to stop it…yet.
Once those telomeres reach the end, the cell quits dividing, and starts pumping toxins into your body. Kind of a self destruct mechanism.
But we all have enzymes called telomerase that rebuild these telomeres. They kick in for repair, so you can heal without speeding up the aging. In fact they should be at work every time it rebuilds muscle due to exercise, slowing the aging of your muscle.
Telomerase also are at work in fetus development. The key is to get these things rebuilding the telomeres for all your cells, or kicking in for every division of your cell, effectively stopping the genetic aging process. At least in theory. (Longer telomeres works on nematodes at least.)
My goal is to slow the aging process enough for technology to catch up. I believe I know enough that (as long as I stick to my plan) will result in be being healthier then the average 50 year old is now, by the time I am 80. (2047) Hopefully 39 years should result in some technological advances.
Oh, and anyone who understands the power of compound interest, think of what would happen to your retirement fund if you had an extra 20 years before you took out that money.
