Video wont work in the UK, but I've seen documentaries about these two. I think they share one of their 3 lungs, have seperate hearts but share some of their digestive system? Then they control the limbs on their side, but since they were born that way they've somehow got it worked out.
What I find most interesting is how they manage to drive and sleep? I imagine they will feel tired at same times, but there must some days where stress or activity has tired one more than the other. Documentary I seen also shown there were hopes at them getting boyfriends, as in like a boyfriend each?? I mean how?
