Ever wondered? I know I have. Although I can’t cosign Astronaut Chris Hadfield’s view on how “relaxing” weightlessness in space is. Just wouldn’t work for me. Besides, can you imagine waking up and looking over to see Hadfield sleeping like this?
Seriously, not a good look, and it ever-so-slightly reminds me of someone. No offense to Hadfield (I wouldn’t want anybody to see me sleeping).
