A sedentary individual without exercise is unlikely to develop problems from a Type 3 acromion due to insufficient repetitive shoulder loading.

“you should have been orthopedic surgeon so you can have a type one one a type two or a type three of chromian type one is totally flat that's the majority of people type two the second most common and type three is about I I don't remember the exact numbers but certainly it's not rare like 30% of people and that's the one that really predisposed you if but only if you're an overhead athlete or lifting weights overhead or doing all sorts of you know aggressive things if you're sedentary actuary who doesn't exercise then um you'll never have a problem because you're just not repetitively loading it enough to wear down or cause a tear”

“you'll often hear people talk about um you know well I can do so and so and I've never had an issue therefore it's okay right so if you're if you have the top AC chromian there you can probably get away with a lot more overhead activity and you might look at somebody who's in category three who every time they do excessive overhead ity gets injured and you might be saying well there's something wrong with you the reality of it is it would be interesting if we sort of knew these things in advance and we could maybe modify and temper our activity around our genetics effectively”
