You're a sorcerer, and I'm a scientist. So, why don't you give me a spell to try to experiment on objects? My team and I may find the answer to your question that way.
Also, i have a secret ingredients, in fact 2, for "living longer"
But first, a small similar interesting FACT "Return mount hua" once told : "Eat well, sleep well, learn well, do sports, dont skip studies/training, that ez to be successful but people simply dont do it"
Well, to live longer : Drink lot of hot water, be happy/smile
Reason, asians LIVE VERY LONGER, beside DNA, is simply bc of "lot of hot water(tea)"
My cpu is lazy to cite all the benefits....
And "happy"
Well. There are old people in the past, that lived until 100, despite drinking/eating-greasy/smoke/sexing, NONSTOP.
+decade(s) ago, it was quite half common-saying, "smiling make you live longer"
+ villains live longer
@GoodPerson Well, in a way, all of life is about recycling.
