Younger Astronauts Can't Stay Up as Long as Older Astronomers

Young astronauts have to be back inside the capsule by the time the streetlights come on. Young astronauts are also not allowed to stay up as long as older astronauts. The reason young astronauts can't stay up is like literally old people ain't got as many years left for cancer to develop. I say send all the old people to space if they want.
