I'm 6' tall and feel oversized for the world. Any time I have to use a counter, table, wash dishes, etc, I have to bend over just enough to jumpstart some back pain, and I imagine that's a contributing factor to chronic back and neck pain.
A friend looked into it once and found resources suggesting the standard kitchen counter is made for people 5'6". It's long been a dream of mine to get a custom made kitchen made for my own height. Well, it's a dream that follows the dream of owning my own place. One problem at a time.
I am 6'2" and I really connect with this. I am constantly shocked by washroom vanities set low enough that they feel like a child's toy, shower heads set at nose level, and kitchen counters just a few inches below the lowest level that I could comfortably work.
In retrospect, I was lucky that I went to a high school where I was only a tiny bit on the short side, good enough that when I was feeling down on myself (i.e., all the time when I was in high school) I could tell myself "at least I'm average height." I didn't realize until I left home that the demographic people judge me by is quite a bit taller than the demographic of my hometown.

You aim for the center of mass -- roughly at the heart. A bullet, thusly aimed, that drops slightly short can still hit someone in the leg or lower abdomen. Or it'll hit the ground and kick up dirt, be more visible.
A fixed height for each tick mark also means you can use the enemy high to roughly calculate distance.
