I'm one of the people from one of the blue zones (Sardinia), on one side what he said is true, you don't need to go to the gym to be healthy, but by just merely walking a little bit more you will not achieve such a great benefit. All the elderly people I know have a lifestyle that can be considered weird, for example: - My grandfather goes every single day to farm his land, he spent 3-4 hours every day doing all kind of farm jobs, mostly potting plants and digging the land. Even if he is after his 70 he is stronger than me (and I don't consider myself weak). - My neighbour (an old lady around 110 years old, that lives alone and sometimes you say around 4 generations of daughters at her house (I usually see her in company of her daughter, her granddaughter, her grand-granddaughter and her grand-grand-granddaughter) wakes up every morning before the sun can raise and goes to the fields to cut wood and then she carries it on her back. - My other old neighbour wakes up every morning very early to, and goes to farm, he his nearly never at home and hangs out with the gang of old people (it's not a gangster, they simply walk around the village and they sit in every bench in every square) To summarise, I think the difference is the mentality, the people I know, old or young have all in common their absurd stubbornness, all these people loves their work, and even after going to pension they want to continue working (many says they will work until death), many of the elderlies weren't farmer before pension, but they choose to start doing it instead of doing nothing, essentially is people that don't like to lay on the couch and watch the TV, but instead going on the nature and pass their time there. Also many of these people have some unhealthy habits, like drinking insane doses of wine, beer, limoncello and mirto. There's a ton of other differences, but I don't want to write an article in this comment
