Pinpoint 'Anti-Aging' Genes
Some scientists have discovered a set of "anti-aging"
genes in animals that -- when manipulated -- have similar
life-extending effects as calorie-restrictive diets. Correspondent
Tom Bearden reports on the research into the relationship
between genes and aging.
scientists investigating the link between genes and living longer
discuss the how the genes work and what the ramifications of an
older, healthier population may be. In addition, a student describes
her experiences on a calorie-restrictive diet.
