DrFrasierCrane writes: You think you feel weighed down when your dentist lays that lead apron on you to take X-rays: how about the doctors who deal with radiation treatments and have to wear those aprons all day long?

It is back-breakingly heavy and doesn't cover the body completely." The zero gravity suit eliminates the weight and the exposed openings. Link to Original Source
