That is a good tip but if he is worried about safety he should do something with his hoodie pull strings hanging down. He is more worried about skewering his head with a screwdriver than getting his face pulled down into rotating machinery.
He does talk about the cords/strings near the end of the vid. IIRC
It's a sign of the sue-crazy environment we live in, I think.
I've seen a lot of disclaimers/cautions/don't do as I do kind of statements.
But, we're grown-up here, right?, and should know which end of the screwdriver to stick in our ears.
I posted it just as a kool twist on an old shop trick.
Thanks for watching.
