Doing the IT thing, and still playing a viola on occasion, I have retained a good amount of dexterity in the joints betwixt my various phalanges as I continue to mark off the decades.
Despite also being a shade-tree mechanic, DYI home dude, and a weight lifter...
A bit like the hippo ballerina from the old cartoons.
LOL!
Yes, I crochet, knit and type, which keep my fingers fairly nimble, but some days, the stiffness is beyond my abilities to overcome. Then it’s like trying to manipulate a bunch of Teletubbies at the ends of my wrists.
