As far as the back flab on my arms, I'm trying to convince myself I won't know anyone so don't need to be embarrassed when the stanard is Britney Spears LOL.

Slightly off-topic, but a friend noticed the "Queen Elizabeth wave" where her forearm is held straight up from the horizontal upper arm, and her hand moves in a twisting motion. The arm flab doesn't keep waving for five or ten minutes after you quit waving when you use that.
My kids find it amusing - but they're still young.
