It has been reported that Albert Einstein explained his theory of relativity this way:

If you spend two hours speaking with a beautiful woman, you feel, at the end of the two hours that you’ve spent only two minutes with her; while if you spend two minutes sitting on hot tin, you feel you’ve spent two days!

I recently stumbled across a graph that seemed to convey the same message:

Perhaps these examples will work for those who have never spent time with a beautiful woman.
