I also rule that elves and other long lived races gain less after they get to be around a 100 because their nerve cells can heal better than a human's (our brains only get worse, we never repair neural tissue). The advantage is that elves have longer lives, but they tend to be more "forgetful" because the neurons that handled the information are no longer there. So after a hundred years their exp gain slows down to 20/year because they have to take time to re-remember the stuff they already learned.

As has been mentioned, humans are constantly rewiring their brains. It's a use it or lose it muscle.
90% of the cells in your brain are not 'brain' cells, but rather support cells that digest dead neurons and perform other support functions for the brain (Yes, that means there are over a trillion cells up there

Granted, we don't have the continued cell stimulation rate a bird does, but then again, no mammal does.
