You're not going to get a statistically valid result from a poll on WAYGOOK.
I just finished orientation with 50 teachers. There 7 of us over 30. The bulk were in their first few years out of college.
I'm 22, and the youngest ESL teacher I've met out here in 2 months.
I have to say - I wonder the same thing myself on waygook - from some of the answers, I can say - I think the age is varied. I am 40. I am wonder just how many are the ages between say 35 to 45 or older - I was debating on asking the same question - possibly polling - but I have met more under 30's than any other age range. So I wonder the same thing. Whatever the age - I think its great that people have taken the leap to teach over seas. I think it takes more bravery when your older - because your taking the chance of uprooting a settled life back home, (unless your like me and didn't have one to start with) but I think its a big leap either way. As far as age is concerned, its just a number, it doesn't keep you from being who you are if your true the person you know yourself to be. Age doesn't always create wisdom, and youth doesn't always create foolishness...somet imes its the opposite.
