But what does the science say?
A recent study in the journal Nature suggests calorie deprivation does not extend life. Contrary to previous studies, this long-term study done with monkeys showed that while the monkeys who ate less were healthier and looked younger, they did not live significantly longer.
How to extend human life is being studied at research institutions here in Oregon and elsewhere across the country. Some focus on genetics, others on diet, and one researcher in Chicago has launched what he calls a Manhattan-style Project to slow the aging process.
What do you want to know about the science of extending human life? How long do you expect to live? What are you doing to make that happen?
