November 21, 2013 Men and women who were regularly munching on peanuts or tree nuts in their 30s and 40s were significantly more likely to reach their 70s, a study found. Researchers say they aren't sure why nuts promote longevity, but they think it has to do with how they affect metabolism and satiety.
September 25, 2012 Korean researchers have found that eunuchs who worked for kings in ancient royal courts lived longer, on average, than other males who were in the inner circle. The provocative findings fit with other work that has shown an inverse link between longevity and reproduction: the greater the fertility, the shorter the life span.
August 30, 2012 A study, which started back in 1987, shows that monkeys fed a diet with 30 percent fewer calories than normal did not live unusually long lives. Researchers say the results are a good indication of how caloric restriction might affect the life spans of people.
