Hmm, is that someone Tambako? :-) I think this programme is for everybody ... it's kind of tourism. It cost almost $1900 for two weeks. Which is about a half price of full price as guest but we are talking about Africa. Tourism is expensive but living there is super cheap. So this is, probably, just another way to profit. But it is ok. It's like spend money for charity and being part of it for a while. I think everybody can do it. Even those who have kids. Only difference is that you will spare there only two weeks or so. $1900 for two weeks stay is not really cheap anyway. But you'll get your nice meals, laundry, electricity and WiFi.

There are real volunteer opportunities in Africa but those are probably in different comfort and much more dangerous.
