Probably because it's a completely unrelated question. Height and weight are only similar in that they're both descriptors of something physical. That's... pretty much it. Height is basically immutable. More of it is not bad. Less of it is not bad. It's not particularly reflective of lifestyle outside of simply not being malnourished. It's just... there.

Weight, obviously, is nothing like this. It absolutely comes off like you're trying to be snarky.
