This LEF News reprint isn't new news, but I wanted to point it out as a reminder of the difference we can make to our healthy life spans using only the simplest of methods available today - exercise and diet. Radical life extension and working anti-aging medicine have not yet arrived, but we have a fair amount of control over whether we live to see them. "A recent study conducted by UF found that mutations in the energy center, or the mitochondria, of a cell were caused by obesity and lack of exercise, he said. These mutations can lead to apoptosis, or programmed cell death, and may be directly related to the aging process. ... People don't respect food, they abuse it. Fifty percent of the U.S. is killing themselves by not being physically active and having a poor diet. ... By respecting your life and respecting your body, you could add 30 years to your life span. It's that simple."
