Even King Solomon, when discussing a man's life, opened with this statement in 1000BC.
Ecclesiastes 1:2 (KJB)

Psalms 39:5b (KJB)
...verily every man at his best state is altogether vanity.

If you wanna watch a very interesting BBC Documentary series on it. Look up "The Centaury of Self" on Vimeo, it's fascinating to say the least.
