I recently saw an interesting documentary on the first emperor of China. (Which refers to the man who originally unified all the different parts of China. "Unified" being a euphemism for "conquer", or in other words, kill everyone who says you don't get to be Grand High Poo-Bah.) He's responsible for both the Great Wall and the famous terra-cotta warriors, which were set to guard him in the afterlife from all the enemies he made from doing all that "unifying". (Does that make him a "uniter", not a "divider"?)
Interesting thing is, while his tomb was being built, he apparently decided he'd rather just stay in this life, and was in search of immortality. While he searched, he wanted to at least prolong his life as long as possible. Advice from his doctors? Have a lot of sex and eat a lot of mercury. There doesn't seem to be any evidence that the doctors were secretly trying to kill him, either.
What strikes me is this: What will people in 2000 years think of our longevity advice? You know, all this stuff like "exercise", "eat lots of vegetables and fiber", "avoid sugar, salt and fat", etc. What if this is all considered just as ridiculous someday? Who wants to take a risk like that?
Think I'll have a pizza for dinner.
