“A note about sunglasses: Some folks should be wearing them. For instance, a lot of the fisherman in native tribes would go blind at a fairly early age from staring into the water for long periods of time. The Eskimos had really cool bone sunglasses, with little slits they would use, so they would not go snowblind. After my own daily sun exposure, I’m not averse to putting on my shades.”
