Kind of obscure, but in engineering circles, there is an old saying that sums up the second law of thermodynamics: You can't push a rope. I am surprised that this has any currency with engineers, who are normally bright, innovative people. Eventually, someone has got to take a rope into the shower with them, lay it on the roof overnight in January (or winter wherever you are), and push it to class.
As long as I am getting scientific, what goes up is coming down. All you have to do is change your frame of reference and what falls down must go up.
Note that pigs do not sweat, they pant, but you never hear of anyone panting like a pig, do you.
If I get too big for my breeches, and it hangs out the cuff, will I get locked up. Hal, you want to clear that one up for us?
