In the most literal sense, the world is not built for lefties. Right-handed people, myself included, are usually blissfully unaware of the struggles only left-handed people understand. When it comes to hand dominance, the world is wrapped around our right-handed fingers. I’d estimate I think about which hand is my dominant hand roughly zero percent of the day. This, however, is not the case for the ten percent of the population who are left-handed.
