As we get older we learn more and more and our brains have to grow in order to contain all our new knowledge. The pressure forces the grey matter out through our pores and it discolours our hair. Just remember that when you see grey-haired people they're pretty smart.
Mind you, they're not as smart as bald people, because as the Psalmist wrote, "The Lord one took a lot of pains to make sure he was fair; to some of us he gave the brains ... you others got the hair."
