I don't know anyone that isn't seriously fucked up with injury from lifting heavy weights.
If you want to be on the Jon Pall Sigmarsson longevity workout plan, go for it.
Your points might be valid but you are mixing up issues here, Sigmarsson died much younger than one is expected to, but that wasn't linked to lifting heavy weights - it does seem he suffered quite a few injuries, I haven't followed him closely, but high level athletes usually have to deal with quite a few injuries, probably more in Strongman and Powerlifting than Curling. Remember reading stats about the number of teenagers aspiring to professional sports who get career ending injuries, outside of strength sports, and the numbers were quite scary (my son recently switched his "passion" from kickboxing to BMX, and I wished he moved back to kickboxing, what good BMX riders do looks like a multiple fracture in waiting, and they seem to collect quite a few of those - I'm particularly afraid of spine injuries) :
https://en.wikipedia.org/wiki/Jón_Páll_Sigmarsson#Powerlifting
"On 16 January 1993, Jón Páll died of an aortic rupture while deadlifting in his gym, Gym 80 in Reykjavík.[17][18] This was likely the result of a congenital heart defect that affected other members of his family,[18] which was exacerbated by his use of anabolic steroids.[19] He had sought medical treatment in the United States the previous year due to heart problems and Sölvi Tryggvason in his 2013 biography of Jón Páll stated he suspected Jón Páll knew he was close to death.[20]"
Definetely an interesting entry in a Death by Deadlift thread.
