Policeman effect in reverse
No matter how old I get, spacemen and women still seem to get even older - and the pace of their aging is, if anything, accelarating. It's as if NASA spaceships are so old and clunky that they suffer from some sort of reverse time-dilation effect. There was a period when people going into space were in their thirties: this lot look like they belong in an IBM Global Technology Services Team, or something.
Does NASA have some sort of rule stating that states that you have to be more ancient than the firecracker they send you up in?
