Just about everyone is proportionate to begin with. What makes the difference is the body type: muscular, obese, skinny or if the dude is slouching. Some tall guys slouch bc they feel uncomfortable in their height.
Clothes fool the eye when we tuck in our shirts or let the Tshirt hang over our pants.
I've found that wearing long yet good looking Tshirt over my jeans makes me look taller and just overall better than when I tuck it in my jeans.
We can get away with 15cm of lengthening but we need to dress for it too.
Apotheosis is a pioneer when it comes to body transformation. He must be the first person ever to change that much about himself. Healthy or not it doesn't matter bc it's not our business. I can actually relate to it coming from a family where everyone is tall - except me.
