Q: Why has nobody been to the moon in such a long time?
A: That’s not an eight-year-old’s question that’s my question. I want to know, but I think I know – because we didn’t go there and and that’s the way it happened and and if it didn’t happen it’s nice to know why it didn’t happen.
So in the future, if we want to keep doing something, we need to know why something stopped in the past that we wanted to keep it going.
