Singapore - heat yes, but oh lord the dreadful humidity. Spent most of my time there feeling like a soaking wet piece of string. Can't do humidity.
Absolutely love beautiful New Zealand despite it trying to explode all the time - apart from the sandflies of course. Bastards.
Love Australia too, except for the rainforest bits (soaking string syndrome again). Mind you, some of the worst wet weather ever the times I've been there has been the east coast. Come to sunny Australia? Pah - it's a con.
.
South Africa has a lovely climate, except when it rains so hard that the ground is covered with really sweet little frogs running everywhere.
Didn't like the Middle East - too much sand and crap attitudes to women.
Love most of the Mediterranean countries for living but didn't like working there so much: am too much instilled into northern European work ethic and efficiency.
India: now there's a culture shock!
China: haven't worked there for 15 years now but every time I was there I realised that was the future - must seem even more so now.....
Having spent so much time in so many countries I still think (with some exceptions) Britain has some of the loveliest scenery in the world.
