i noticed that some people are saying kids should be able to work.. I agree,because if you're stranded on the island you would need an 8 year old kid to work!!!it should be like they can start farming at 8(it's not that hard to pick vegetables!!!),building at 10 (they could like get wood and rocks since they can run,and the adults could do the hammering)then research and healing at 14,then breed at 18.
