When you have the chance to fight for victory or a podium finish, you have the motivation to push that extra bit out of yourself.
Niki LaudaYou have a brake in your brain that stops you doing stupid things. The older you are, the earlier that brake comes on. When you're 20 you stop at nothing; when you're older you're cleverer than when you're 20, so your brain brake operates more often!
