Speaking of longevity, my grandparents are almost ninety years old, and it is really normal to keep in good health. As far as my grandfather is concerned, he seldom eats greasy food, but he insists on drinking tea regularly every night and goes to bed early, almost before eight o'clock.
In addition, grandpa never sleeps late and gets up early, about six or seven o'clock. After getting up, he will do morning exercises and run, and then eat.
Grandpa has a habit in winter, that is, he likes to eat frozen pears and some cool fruits. It may be because he usually exercises, so he never has stomach trouble, and every five days, grandpa goes out and goes home by bike for about an hour.
Besides that, grandpa gave up smoking several years ago and never drank.
