Dear John:

This is what drives me up the wall about this list.

You pull out numbers, but do not mention where. I know you cannot
prove these numbers. But could you at least give us some idea where
you got them?

Frankly, nothing is simple. A few trips into space and we have more
experts and more views of what's fact than we do astronauts.

I hardly know you. Give me some reason for your figures. I am
sorry, but your word is not good enough.
