Wendy, you really didn't address Don's question. He aksed about teaching jobs for older people in KOREA. yes, China is much easier for an older person to get a job, but Korea is more difficult. I am 50 (in three days,send those birthday cards lol) and it was much harder to find a teaching position in Korea than in China - even though I have 27 years certified teaching experience and two masters degrees.

Don, what budda says I agree with - hang in there and keep trying if korea is your goal - if you are willing to go elsewhere, Wendy is right about China.
Good luck!
