One of the neurophysiologists with a particularly good sense of humour during the final medical certification asks Mark to bare his teeth. We're still not certain what that has to do with neurophysiology, but this department asked Mark to do a whole bunch of unusual things during his stay in Star City. We think the point is that cosmonauts have to be willing to follow instructions, even when those appear unusual at first sight. In the background is Sasha Kulov, Mark's fantastic Russian flight surgeon. |
