 We're back with Robert Zimmerman, our space historian. Robert, Buzz Aldrin, Apollo 11, still kicking, isn't he? Yep, still kicking, still going strong. Bless his heart. It's great. You know, it's interesting that this is a gift. You mentioned the Van Allen Bell. Notice how old a lot of the astronauts are, how long they've lived. It surely did not affect their life expectancy. If anything, it prolonged it. Maybe. Who knows? We really don't know.
