They also discovered that weight gain increased longevity. Those who were slightly overweight — not obese — had a 3 percent reduced chance of dying before their 90s.
“It’s not bad to be skinny when you’re young but it’s very bad to be skinny when you’re old,” Kawas noted.
Furthermore, subjects that practiced a daily hobby for two hours were 21 percent less likely to die before their 90s, and those who drank two cups of coffee daily were 10 percent less likely.

Scientists now hope to continue their investigations to confirm their findings and consider how genetics may also play a role in longevity.
