Cut down on meat and eat lots of veggies if you want to live longer.
This advice comes from two siblings and their brother-in-law, who, collectively, have lived for 313 years.
Ben Mabuza, the eldest of the three at 112, has lived through more than a century of hardship and resilience, and has outlived his wife and most of his 15 children. Only his middle daughter, now 70, is still alive. He attributes his longevity to a disciplined lifestyle and a vegetable-rich diet.
