Green tea drinkers seem to stave off the effects of old age better than non-drinkers.

Following nearly 14,000 adults age 65 and older, they found that people who drank the most green tea were the least likely to develop “functional disability” over the next three years.

Functional disability refers to problems with daily activities like going to the store or doing housework, or difficulty with more-basic needs like dressing and bathing.

Not only their mental and physical health was better but also their emotional well being and social lives were better, as well.
