Just heard a fun interview with him last night on the CBC from Star City, Russia, and one of the questions asked was if he was dropping a lot of stuff. He said he was surprised after 5 months that he wasn't. He said after the first shuttle flight he did it all the time, much to his embarrassment, he'd try to "float" things over to people like he did in space, and would be surprised with a "thunk." He expected to have the same habitual behavior this time, but that part of his brain seemed to figure gravity out this time.
He said it's been a fascinating experience, that they've been learning a lot of interesting things about how the body and the mind works. Learning about how mechanisms actually work. I'm sure there's going to be a ton of papers out of this summer (he's pretty much a human guinea pig til his body returns fully to "normal" which he said should be in August.)
I can't wait to see how some of this info affects medical school teachings. When it starts trickling into the class rooms. I wouldn't be surprised if we start getting some of the new info in our Gross Anatomy Course this year, since the clinical correlations part of it is taught by my friend Scott and some of his NASA docs.
