Knackered

Spent the day doing a little catch up on home chores now that I am not commuting to Houston every week. Started to paint the sun room. Up and down a step ladder all day long. If you go up and down enough times you realize that you have climbed the equivalent of a 15 or 20 story building at the end of the day.

According to the Laws of Physics (Conservation of Energy), my net work after all that up and down is Zero - but my legs don't believe it.
