It’s really important for many kinds of instrumentalists to maintain good callouses, particularly zouk, mandolin, and guitar players. There’s a rumour that Stevie Ray Vaughn used to superglue his callouses back on if they fell off.
Somehow my left-hand (fretboard side) callouses have all disappeared. I’ve been playing all week but in the shower yesterday I was like, “wait, my fingertips on my left hand feel really soft, what the hell?” now, well, YEP THEY SURE ARE.
A few hours of playing tonight seems to be bringing them back, but… da hell?
