My father also was a MAGAt, up until his death. I'm pretty sure it's not genetic, thankfully.
If you do start to thin, there are a ton of treatments to prevent and reverse it. As long as you get on them early, you'll likely not notice much of a difference. I was just super poor when I started balding, so I didn't have a choice. Now those poor follicles are toast.

Same with "the customer is always right" having "in matters of taste" added to it as the alleged full version around the same period.
Not only is it wrong, it ignores the entire narrative that led up to the original saying. Retailers asked their front-line staff to tolerate customers's unreasonable behavior to increase sales. That's it. The revision shifts the blame to the customers, who should be civil regardless, but would be more likely to be so if acting otherwise didn't have few consequences and the possibility of greater material gain.
