The only real skill I've retained from my younger dancing days is the ability to internalize sequences of physical movement very quickly.
...and after you get a single silk footlock on put on a half body flag on the same side and then use your hands to put the second foot lock on your other foot, then use a split silk body flag to get into cross-back.
I have lost flexibility, grace, and strength, but I sure can remember translate a set of verbal commands into a string of connected movement. I mean, I know how, at least. Getting my body to actually DO them, that’s another issue.
