It actually makes a lot of sense, to me anyway, why the left portion would be more heavily weighted.
6’-0” and up is pretty rare as far as the world goes. 6’-5” is kinda the ceiling for humans barring some exceptions and there are plenty of reasons to stop growing on the way to it while there isn’t really any way to grow bigger.
I bet, but even I think that and I’m much shorter. Most of my life I’ve phrased it as I’m taller than average but not tall. But people seem to be shrinking faster than I am: it really seems like I’m taller than more and more people as time goes on
