It's a bit of a no win situation really - it may be cheaper to live in the Philippines, especially in the provinces, but you do need a fair bit of capital to tide you over, buy a house, a business to generate income, etc. Then theres health considerations - its free in the UK, but not in Philippines, and what happens if it all goes wrong, you gotta come back and start all over again.
