Well, we all must go. I hope he died at home, calm and surrounded by his family.
Our body is designed for 200-300 years of life. Only it is necessary to lead a correct way of life.
We're actually living far longer than previous generations, heck, far longer than those from more ancient civilizations that supposedly got everything figured out. This is despite all the pollution and the food we're eating. Even citizens in third-world countries would live longer than the middle-class in say, ancient Egypt.
I wouldn't mind living up to 300 as long as I look just 30. Unfortunately, I'll probably just look like a raisin.
