flungdung,
You're absolutely right. The sports facilities in Abu Dhabi are considerably better than in Nigeria, where it very much depends on who you're working for and which contract you're on as to whether there are any facilities at all!
Even withouit a car you can still get out and about in Abu Dhabi as there are often others willinmg to give a lift, or you can call for an 'Al Gazelle' cab.
As for UK - can't understand why anyone would want to live there. It's cold, expensive and the taxman is not nearly as understanding as if you live in most other European countries. I think it's much better, and cheaper, to quit Europe altogether.
