could it just be that in order for the others to survive, they need to reproduce, the pregnancy problem has got to be tied in with the healing powers of the island.
Maybe you can answer a question i have Jadie 90?
In the episode when we saw Ben growing up on the island and the wiping out of the darhma group, Ben was recruited by a man he met in the woods, I believe that same man is the one in the blue shirt in the camp of the other in the episode( through the looking Glass), sorry i don't his name, he is one of the others.
But my question is if it is the same man he appears not to have aged a bit and ben has aged 20 - 30 years ??????????????????????????????
