Some people are born without arms. Tha condition is known as reduction deformity. That means, for some people don’t have arms or legs by default.
This is Jessica Cox. Her congenital anomaly is obvious: she never had arms.

Apart from driving and using a PC, she swims without arms:
performs martial arts without arms:
does all that girlie things with her legs:
