There was a post in absoluteunits of a giant basketball player (Hamad Fathy) who is 7’5” and alot of people were commenting about the likely sad state of his knees and back.
My question is if he is fully proportional and athletic with no extra weight damaging his joints, are the forces of gravity enough to do more damage to him just because of his exceptional size?
What else could slowly wear away at someone that large’s body?

See, there’s the issue.
A bone’s strength is proportional to its cross-sectional area, which grows with “size” squared. Similarly, pressures on joints depend on the surface area of those interaction points, which scales with “size” squared.
But weight scales with size cubed, and twisting forces scale with weight times the size, (or proportional to size to the 4)!!
So even if the body is “proportional”, the forces aren’t.
