I just wanted to see if I could solve all the puzzle in the game before they grow old and die and I fully reseached medicine, so they got a good chance and the bath is completed and the orchard is completed I working towards leadership and constrution. Oh yes I fully reseachered science now. I am sure The Last Tribe will be made up if they all live to see their village completed.
I hope they live long enough, the older members of the tribe.

The answer to the speed question, I play it on slow speed for the same reason above
