Both of my grandparents from dad's side are 93 and still doing relatively well - self-sufficient, nothing horrible looming that we are aware of. Genes, good eating habits and healthy dose of exercise (rather low/medium effort that lasts long like gardening or foraging mushrooms in their case), coupled with obvious things like no addictions... and voila. They both had very good work ethics, on a level I can only envy (thanks to communists that didn't get them far professionally but that's another story and it didn't bother them). Bad part is, all of their friends and colleagues are dead by now. They can only meet their kids' generation.
