The organisation is called Learn4Life and they have two schools; one in Siem Reap with luxurious accommodation for the teachers, and one in a village some 25 kilometres away, with accommodation more suited to the likes of me.
I'd hope to stay a year, so may get the chance to do both.
You can see some pictures on the website.
It has been a difficult few days working up to the decision.
There have been health and financial issues to think about, as well as leaving friends and family behind; perhaps forever this time. But in the end I knew my chances of getting enough work without continual stress and worry were next to zero.
So why not just take board and lodging and go to do something useful in a beautiful and fascinating country?
And I'm sure I will have lots of visitors coming out to see me, and the wonder that is Angkor Wat.
Won't I?
I may get the change to reach the Plain of Jars and travel up the Mekong by boat.
And lots more too.
