Sure. It's ridiculously selfish.
As you age, you realize your success in all things eventually boils down to experience and ability to execute. Ability to execute wanes with age, as experience is accumulated, so it balances out. Now imagine a spry 20 year old with 60 years of experience? Not exactly fair to those actually 20 years old.
EDIT: To the old farts responding below me, regardless of how well you take care of yourself, you wither with age. By removing that, you are messing with the balance that has existed for millions of years. It has nothing to do with fair competition, it has everything to do with using technology to get ahead of the competition, in the same way that some athletes use performance enhancing drugs, and we as a society frown on that too.
