I been playing along with this village for awhile and so they will live a lot longer I pause it every day. The tribe is called The Last Tribe and all the children have all cellectables complete
The next pic is all 22 villagers which 3 out of the 22 are still babies. Attending the lecture. Waikikai is the oldest in the village is age 46

Bravo! Congratulations!

So, you paused the game everyday, but did you play in fast speed? and during how many time each day? And how many puzzle did you solved? I wonder if the game may be solved before all the original villagers die.
Or was it only for getting the collectibles?

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

Ok! Thank you!
Maybe I'll try this in a next tribe!! I hope it works!

Good luck to your tribe!!
