OK, I am going to tell a story, and I swear that as far as I know its the truth.
I was told this by a WG in Middlesbrough, about a second WG we both know. Now this second WG specialises in dom and bondage, not real hardcore BDSM, milder than that, she doesn't have a dungeon or anything.
Anyhow, this old guy, in his 70s, came to her for a bit of rough sex, and halfway through the session he pegged out with a heart attack, on her bed, stone cold dead.
So the WG, after the panic subsides, phones 999, and an ambulance crew arrive, yes he's dead, so they have to send for a doctor to certify this, then the police because its an unexplained death. All these people are traipsing through the house, and the WG is spinning them all the same story, she was standing outside and this old guy came along looking a bit ill, then just outside her door he collapsed, so out of the goodness of her heart she helped him inside and up the stairs and left him on the bed to rest until he felt better, but when she went back to check on him she found he'd died.
Now I doubt if anyone actually believed this story, but it was just to say possible, so nobody actually contradicted her, until the police called for an undertaker to move the body to the mortuary............. and when they lifted him off the bed there were two dildos and set of handcuffs underneath him!
