Well, five minutes and the rest on fast forward, got the gist of it. I honestly thing those body-things could be a godsend - kind of a cross between a wetsuit and a birthday suit. I genuinely believe there's a niche there - all the danger and expense of elective surgery is avoided. Probably a bit sweaty, but a good sweat followed by a good shower is good for you.
But the masks! Dear lord no. On a simple level the panic-inducing claustrophobia involved in putting your whole head into a football. Then, as others have said, they look no more attractive than a halloween mask from the pound shop.
Above all, imagine the explaining if you were in an accident and had to go to hospital.....
