I'm talking about the same animal. Say a litter of mice, one of them will be the runt of the litter and one may grow larger than all the rest. This is not unusual for this to happen. The bigger one is stronger and can withstand greater physical stresses. Same family and general traits-- the bigger one is stronger and more durable
You're talking about people with frames that are taller than their systems were made to handle, due to the effect of gravity on their systems, and that's not what we're talking about really.
But if a larger (but not disablingly tall) person was asked to carry a heavy box up the stairs compared to a really small person of the same scaled frame, the smaller weaker person is more likely to throw out his back. Given it's the same box
Well for bones, the relative density isn't all that different from one to another unless you have a bone disease. It's the thickness. A little thickness = a lot more strength and sturdiness than a little density. When medical scans are done, they check the thickness. The only time they are concerned with the density is in cases of disease.
We're talking about bones, not wood, they are very different.
Tyson's bones are probably a lot thicker than DLH's, anyway. Their frames may LOOK approximately similar in that photo, but we're not talking about relative looks from a distorted picture. DLH is not bigger or thicker than Tyson, but he IS a lot closer to the camera. So that's a bad example. Also who's to say DLH's hands were more injury prone than Tyson's? Because that's what we are actually talking about
Tyson naturally also had a lot more muscle and strength and power to his frame than DLH, you can't pretend those aren't factors. I can't believe you think DLH's bones are/were naturally as thick as Tyson's. That is so wrong
