Besides commiserating about the crude people who paid attention (!) to your arm hair, I should point out that back in my forties I swam in a competitive league with a bunch of other old farts.
Most of them shaved their arms and legs. One guy suggested I do it to give myself a speed edge.
He showed me his smooth arms while I looked down at the beer bowling bowl distorting the streamline shape of his belly.
I smiled and thanked him for his advice.
And with my hairy limbs, I clocked better times than him at the next meet. ;-)
