. Your comments are confusing. I got an OA from Hull with no money in a UK bank. I have also extended an O visa in Thailand because of retirement, so I am not sure what you mean?
. I’m 5 years older than you and also on second Thai wife. Been here 12 years and will never go back to UK, mate. I’m very happy here. Sure it’s far from perfect but I’m going nowhere else!
. Be aware of the financial requirements for an ‘OA’ too. You need proof of income from Embassy (65,000pm). Or 800,000b in your sole Thai bank account for 2 months or combination of both.
I suggest you do more investigations. Most(not every) employer will want to see a degree (of some sort) to employ you as a teacher. A bare minimum should be a TEFL course. Working in LOS as a foreigner isn’t easy. Sure you could open a little private school with the wife, on the quiet but do you really want to start a new stage in your life by continually looking over your shoulder. Piss off a local and then be reported to Immigration for working without a WP. Yes, it’s unlikely to happen but think about it, carefully.
