After University I would like to go over to some of the most deprived countries in Africa, or any nation for that matter, and help teaching or social work of some kind. This is due to not wanting to sit behind a desk 9-5 five days a week like I know I will do if I do not try and do something worthwhile and fulfilling with my life.

Anybody have any experience of this and would they recommend it? And Who are the best charities, organisations, foundations etc. to apply to do this sort of thing?

P.S. I am going University in September.
