When I lived in Cambodia I saw a lot of Abercrombie-model looking guys in their 50s. They were farmers, I think. I’m currently in Italy living with a farmer in her 60s who’s in great shape. The other day she dropped cold into a front split. I don’t want to say farm work is a panacea — I know it depends on what you’re doing and how you do it — but my own experience plus a book by Esther Gokhale have convinced me that healthy work builds your body and doesn’t tear it down.

I do think there’s a lot of physical labor that isn’t healthy. And there’s also labor that’s kind of on the line, like heavy lifting — if done properly it’s safe, improperly and it can cause damage.
