Rich people lead longer lives

Talk about your un-level playing fields: They have higher levels of a hormone called DHEAS (dehydroepiandrosterone sulfate) that's produced by the brain, adrenal glands and sexual organs. From the Wealth Report:

"A striking new finding is that the hormone dehydroepiandrosterone sulfate [DHEAS] that predicts life expectancy also follows a social gradient: less wealth, lower levels of DHEAS," said Prof. Michael Marmot of the university's Department of Epidemiology and Public Health. The implication is that wealth brings freedom and time to eat well, exercise, enjoy various past times and stay closer to family and friends.

Of course, there's nothing to stop you from trying to produce more DHEAS by leading a healthier life, although much of the hormone gets produced in childhood and teenage years.
