Perfect as they are: Conjoined twins don't want to be separated

Conjoined twins Pin and Pan's bond is so strong that they don't want to be separated - even if it proved medically possible.

The seven-year-old sisters, from Thailand, were born with their own heads, torsos, and arms but are connected at the waist.

The duo share a pair of legs, with Pin having control of one and Pan controlling the other, and have learned to walk, dress, eat - and even ride a tricycle - as one.
