Yes, the need for health care just increases all the time. HIV-AIDS is the major problem, but many others remain (malaria, TB to name but two). Meanwhile, those "lucky" enough to live in the West just get fatter!
Personally, I still haven't given up on the idea of the "World Tour". I have talked before about "biomeding around the world". One final fling, then, maybe next year. I envisage travelling light with just a tool bag and a few things. Anyone want to join me? Or, more to the point, anyone want to sponsor the trip? Ha, ha.
