I've heard anecdotes about active-over-100 cigar smokers crediting their good health to the cigars. Ditto with whiskey drinkers. Ditto monks still doing the full daily routine of arising at 5am, praying for an hour, taking communion, etc, etc. Other than "because emotions", is there any reason to suspect that healthy-over-100 people would have some special insight into why they are so far to the right edge of the bell curve? You could also ask mothers of L<=>R -switched babies ( https://en.wikipedia.org/wiki/Situs_inversus https://en.wikipedia.org/wiki/Situs_inversus ) what they did, to cause that to happen. (Yes, I'm well aware that lacking daily routines, positive social interaction, purpose to life, etc. can be quite bad for one's health. And "gotta work!" can check many of those boxes.)
