This is a question mainly for the very big guys.
There's pretty solid science behind how your size shapes your personality as a child and has a strong influence on how you're perceived and treated by others and your self esteem. Being very big for example makes you a constant walking threat just by your presence and you learn to socialize and show warmth early, or to use your strength for productive things like sports as to avoid being isolated. Teachers and adults are way more cautious of you and come down on you much harder for any infraction and your experience with authority tends to be very different from the average sized person. Hence I think the whole gentle giant trope being common.
But I wonder how much that holds as people get older, get jobs and careers and what not. Idk if being a 6'7 300lbs guy has that much of an impact at 35 as it is at 25. Like does it become something that fades into the background? My tendency is to believe that it doesn't but biology has a funny way of sneaking up.
