Are there parts of your body that at one time you could wiggle but now can't? Are there other parts that now wiggle but you wish wouldn't?

I have two fingers (one on each hand) that wiggle very nicely

I can wiggle one and and wobble two.....:)

Nah, I still got it. I twerked my way through college, after all. ;)

  Believe me, it’s not that I can no longer wiggle it, it’s just illegal to whip it out willy-nilly and give impromptu shows. Grrrrrrrr, morals, ethics and decorum.

I used to have very flexible toes and fingers.
Could pick up a pencil or grain of rice with my toes.
Could bend my fingers back like a Thai dancer.

Now the wrinkly skin folds (a year ago filling me out by one size) flap and jiggle when I dance.
The humour and fun of it compensate for the loss of physical beauty.
