How to live to be 200 by Stephen Leacock
is a great satire essay.
It was there in my english syllabus.
Some points of the essay:
how health maniacs exercise regularly but die anyway.
They don't drink tap water.
They eat food which contains protein, starch and whatnot.
Maybe you could look for it on the internet
and gather more information about it.
Good Luck! :)
