I often wonder how much of the "advice" people pass out is something that started as a specific piece of advice for ONE PERSON that was then viewed as "for everyone".
For example, I really CAN'T squat past 90 degrees. Why? Because I had knee surgery, and when I go past 90 degrees, one knee ligament gets caught on a certain part of my knee hinge and goes "pop", and it hurts. I'd never say to someone "Oh, don't go past 90 degrees" though, even though I know that, FOR ME, more than 90 degrees isn't a good idea. I wonder if someone hears this sort of thing and says "More than 90 degrees = UNIVERSALLY BAD" and then starts spreading it?
