It is not that much about diet, it is about having less stress and worries of all kinds, and have good habits, such as mixing periods of physical activity and with total rest (taking naps).

It is not like staying all the time in a passive stress (or depression) - having a high level of stress hormones without any physical activities.

And the last but not least, there are emotion contagiousness - one can see it a subway. "Toxic people" is very real thing.

Then comes the media with its pressure about sex (which is about youth and health) and wealth (which is a weak substitute for the two former), and these material pseudo-achievements that one must accomplish.

All these factors together, plus many more - such as drinking water, air, soil in which vegetables and grapes grown, contributes to longevity, of course. But it seems like there is no one which makes it all - no shortcut, no way to buy it.

I believe it is much more about the state of the mind, which influence everything, including inner bodily processes and rhythms. Mind is first, environment is second, adversaries is third. ''Hell is other people'', you know.)
