Science and mathematics have never been my strong suit, but I am convinced the reason the Earth doesn't fall out of orbit is that you and I each spend our days carrying it on our shoulders. We each lug around one quadrillion, seven hundred fifty-six trillion pounds on our back. It is no surprise we have lower back problems. God forbid someone trips.

Think I am wrong? Tell me how you feel on those days when nothing is working for you.

What does your sense of humor look like on these hard days compared to your best days?

The absence of laughter and jokes are the first indication...
