I lived in the Philippines for a year when I was 24, as a single guy. It was probably the best year of my life!
But having said that, I was glad to get back to the UK. I found that I missed quite a lot of things, like cold, clear mornings, sunday roasts, family & friends, decent TV channels, custard......
Since then I have enjoyed many, many holidays in the Philippines and now that I have a filipina wife, that will continue. But I'd like to go back there again for an extended stay, but I think that will have to wait until I've retired!
But overall, I'd highly recommend living in the Philippines, even if it is only for a few months. It's the best way of properly experiencing the country.
