Ideas on Living Longer and Healthier

Regular exercise and the practice of calorie-restriction with optimal nutrition are shown to extend life in laboratory animals. However, only calorie-restriction reliably extends maximum life-span in addition to raising the average.

On the other side of the scale, becoming fat and sedentary are shown to shorten life-expectancy and make health worse in laboratory animals and are associated with that same outcome in humans. The amount and quality of evidence for these points are the gold standard against which other claims about health practices should be measured.

Any responsible physician will tell you this: No presently available technique or medical technology has been shown to do anywhere near as well as exercise and calorie-restriction for a basically healthy individual.

So don't go hunting for silver bullets that don't exist - there are always people out there willing to sell you a lie.

It's the sad truth that you can't exercise your way to living to 100; a majority of even the fittest people with the best diets die of old age and its complications before reaching 90 with the present medical technology.

However, improvements in medical technology is the key. Progress in medical technology is the greatest determinant of how long you will live and how good your health will be when you are older. Thus the more you can do to speed development towards therapies capable of human rejuvenation, the longer you will likely live: learn which research should be supported, make donations, and persuade your friends.

All of that exercise and calorie restriction is just there to raise the odds of living to see the day on which aging can be reversed. It cannot be a magic wand to live longer.
