Shift
Time plus gravity equals shift.
We're not talking time-space continuum here, we're talking time/gravity/shift, or what happens to body parts as a result of time and gravity.
You might say this is a paradigm shift, as in the stretchy elasticity of young skin compared to the sagging stretch of post-motherhood skin.
SHIFT
Breasts shift, buttocks, tummys, chins shift with time and gravity.
SHIFT HAPPENS!
Did you know that ears continue to grow with age? Cheeks turn into jowls, eyelids sag, uteri tilt. In religious circles it is known as:
HOLY SHIFT!!
There is nothing religious about it. Shift happens. It is all happening to me.
OH, SHIFT!
The moral of the story is:
Nudity is for the young in parts.
