My curiosity is piqued too! I’m mostly commenting so that I can check back later, but…

• Are they wearing chain mail gloves (for sharks or cutting meat) that the hair would catch?

• Going forearm deep in food, to stir or, I don’t know…?

• Reaching into hot ovens or crucibles that the hair would singe?

• Going forearm deep to help birth sheep or cows?

• Or are they a wristwatch/hand model?
