Quiz of the week, huh. So the big question is whether microgravity scrambles our DNA, and the answer is apparently a multiple-choice exercise. Cute. Here’s what nobody bothers to mention: astronauts are a sample of about a dozen people, mostly middle-aged, mostly from the same two space agencies, flying for six months at a time.
