This is why I don't even lift....
Not.
I just use the rack, never killed my self.
Crazy story though, my cousins fiancé doesn't in exactly this way. It was like 15 years ago now I guess and he was lifting alone in his apartment and just had a bench set up and was fairly strong I guess.
He went missing for a few days finally the police or fire department or somebody axed down the door and they found him still on the bench but dead as fuck.
It's all good though, in the haze of crippling depression my cousin went on some fuck binge across Europe and met a much cooler husband (who trains legs too rather than just bench). Cool guy, he's a firefighter and was in the marines for like 10 years.
