Ninajifunza kiswahili pole pole :) (Your question did go over my head, but it did allow me to learn many new words :) Asante sana!)

My wife and I chose Tanzania for various reasons, including:

- We knew Moshi from some years ago (we climbed Mt. Kilimanjaro), and have sentimental attachment to the place (I asked my wife on Uhuru peak).

- We knew our son (1 year old) would be safe (good medical care, few mosquitoes and nasty animals, varied food). He made friends with our neighbourhood kids pretty fast :)

- She had some connections with a local NGO and so could work as a volunteer here.

- We remembered Tanzanians to be the most welcoming and friendly people we've ever met (and we had the chance to travel a lot). We were wrong BTW, Tanzanians are even more welcoming than we remembered :)

- Kiswahili is a challenge to learn, but we like learning new languages (we take lessons bi-weekly)

- It's much more attractive than most places for our family to visit during their vacation ;)

- I always echoed Mark Shuttleworth's sentiment that "Africa is the future", and I decided to put my actions where my mouth is :p

I could go on for a long time, we really like it here.
