Quote from Fractals 'R Us:
I saw a drunk guy in Mexico throwing his baby 10 feet in the air and catching it once...
In that video the kid would be making some pain noises, being held by one arm and swung around is going to get some response one might think... and if the kid was getting that kind of treatment before he would not go the adult all happy like he does maybe...
Babys have more flexible limbs than older children and adult. No pain possibly. The fast constant motion is overstimulating for the babys senses, he can not react but becomes overwhelmed of the stimulus. It could give him brain damage when his brain is forced against his skull over and over with the motion. I hope it really is fake.
