Is it too late to become a dentist?

I was at the dentist's yesterday for my regular check-up. My dentist and some of his dentist pals travel once a year to a place lacking dental care and tend to patients for free. Last winter, they went to Mongolia, where I gather the poor guy just about froze to death. This year? It's Fiji - or, more precisely, the second-largest island in the chain including Fiji.

Because, out of 130,000 people who live there, not one of them is a dentist. Yep, not a single dentist on the island.

So, if you know anybody who wants to (a) be a dentist and (b) live in the South Seas, you might want to give them the heads-up.

It's almost enough to make me want to be a dentist....
