You can't have a long longevity if you are not emotionally & mentally stable.

A study was made (I don't have the link for it) that compared people who lived for more than 100 years, and the habits and behaviors of these people were very variable, some people even smoked.

But 2 interesting things that they all shared in common was:

- They usually never traveled

- They wouldn't be too sad in the presence of adversity, they would face life's daily problems with good humor
