A bizarre Indian Muslim (and, apparently, Hindu) ritual of throwing babies off of a 50 foot mosque:
Here are some of the physical consequences of shaking a baby:
The brain rotates within the skull cavity, injuring or destroying brain tissue.
When shaking occurs, blood vessels feeding the brain can be torn, leading to bleeding around the brain.
Blood pools within the skull, sometimes creating more pressure within the skull and possibly causing additional brain damage.
Retinal (back of the eye) bleeding is very common.
