Now it all makes sense to me...

This must be why I have aches and pains all over my back, my knees, my arm, my stomach...

Silly me, I thought it was just because I just turned 36! (Or from when my son and I fell down the stairs the other day - but that's another story) Turns out, I'm just terrified beyond the capacity for rational thought! How liberating!

Well, that makes me feel much better, now.
