oh the gravity of the matter

Thank you, Treker, that sounds logical to me! I think you hit the nail on the head.. (in carpenter's lingo, how about that one, Trek?) :)

Funny, titmouse! That's true in my house.

I can only surmise that the force of gravity would be greater on the reclining "individual" because of the greater surface area. The standing "individual" would be have less surface area when erect.
That's a carpenter's "take" on the subject. LOL

Yes, was hoping someone would come along and explain this one..

Treker, thought you might be the one for that.

You and me both, Pinkie.. Thanks for the comment!

I do not understand the mathematics of this puzzle.

Verrrry interestenk!
