If you live to 100 sure, well done! If you live to 10,000 then you have used far more than your fair share of life. I would say a man's mind is a great waste of life and death is all the resolution a lifeform should need. Consider the insect that hatches, matures, breeds then dies in the space of a day. That is perfection in life and evolution. Thinking that the longer we live the more life we have is false.
When I die I am going to ask to be fed to a tiger shark or something. That's selfish of me, but i would rather become part of something great and powerfull, near perfection of evolution, rather than worm food. That's the 'give' for the 'take' of being born. The take of living, of killing to eat. To return that to another creature is noble. To live forever, constantly consuming, is evil.
