We laugh, but I've found that it can be true (up-hill in both directions)!
Let me explain...
I used to ride my bicycle around the top of a large hill. It went up and
down, but I ended up in the same place that I started. One would think
that, since I ended up in the same place, I necessarily went up-hill and
down-hill the same amount - but not true!
It took me an hour to ride around that hill. The up-hill parts were hard
and I went slowly. The down-hill parts were fast and easy. Turns out, I'd
spend 45 minutes going up-hill and 15 minutes going-down-hill. Not equal!
So, while I may have "theoretically" went up and down the same amount. In
terms of time and my perceptions, it was up-hill most of the way!
