And teeth. And corneas. There are quite a few things that only last long enough to get you sufficiently past child bearing age.

Of course, old people can learn new things so I always thought the "neurons don't grow" thing was silly (although I guess it's possible that we have a set number of neurons and it's just our synapses that keep growing).

Hmm, Teeth do regenerate, but only at a certain rate, hence holes and stuff.

Those people who loose saliva production end up loosing teeth as well, because the enamel disappears.

I have no idea about corneas.

Do teeth regenerate? A quick search for 'tooth enamel regeneration' turns up a bunch of pages saying it can't regenerate, and a couple about some researchers who found some treatment which does let it regenerate somewhat. I hope you're right, though.
