How astronauts sleep on the International Space Station - GIF

I could probably get used to that quite easily. Since I used to be able to catch an hour's worth of relaxing sleep while standing at Parade rest during those long boring instructional indoctrination formations or for some equally mind numbing parades I could spend 8 hours out there and be just as fresh at the end of the day as the beginning. no one ever knew how I did it I don't think. At least I was never called out for it.
