The Incredible Shrinking SJG

This morning my gynecologist, a nice gal who delivered my uterus 15 years ago, will casually remind me, once again, "You're shrinking." After that update, the conversation will go something like this:
"How much?"
"Half an inch since last year."
"What gives?"

"Gravity."
"Gravity's to blame?"
"Gravity's dragging you down."
"Great."
"Eventually, gravity will drag you six feet under."
"Wow. You really went dark on me."
"Slide forward and put your feet in the stirrups."
