I had a look around some website last night. Some of them had a age 50 cut off. One of them had a cutoff age of 52, which is just weird, but most didn't care, particularly the online sites where I could, for instance, teach in China from the comfort of my own living room, as long as I were willing to wake up pretty early in the morning.

The contracts in the middle east look so cool, and they pay so well. I'd love to spend a year teaching somewhere like Saudi Arabia. However, most of them want a teaching certificate and several years of experience, so I don't think I'll be doing that!
