A study published Wednesday found that rapamycin, a drug used in organ transplants, increased the life span of mice by 9% to 14%, the first definitive case in which a chemical has been shown to extend the life span of normal mammals. Anti-aging researchers also expect a second study, to be released this week, will show that sharply cutting the calorie intake of monkeys extends their lives substantially. The experiment is said to be the first technique shown to retard aging in primates ... The Wisconsin study, which began in 1989 with 30 monkeys and added 46 more in 1994, is an effort to test calorie restriction in an animal genetically closer to humans. Researchers have known since the 1930s that eating 30% fewer calories than normal lengthens the life span of mice. Half the monkeys were given a normal diet, and half had their food intake cut back by 30% at roughly age 10. The Calorie Restriction Society's Mr. Delaney, who has seen the results, said that after 20 years, only 20% of the calorie-restricted monkeys had died, compared with half of the monkeys on a normal diet. He said calorie restriction seemed to slow down the loss of nerve cells in the brain.

I would prefer to enjoy what time I may have rather than merely existing a few more years worried about how many calories are in that piece of lettuce I'm thinking about eating.
Damn right, the only reason I and my wife quit smoking is because of our daughter.
