Without going into detail, that's incorrect. There's a video posted on Nick's channel where a Doctor explains the most likely reasons. I don't endorse Nick's channel but advise you to check the video. It was discussed here on GetBig years ago but the Doctor explains it in more detail.
That may be true, but I've heard interviews with people and I think Steiner, and he listed his botched Trach as the reason. He could of course be lying, and I'm of course no doctor, but that's what he said.
If you believe it to be some other reason, that's cool by me. I'm just glad I don't have that thing in my chest and for that, I'm lucky enough.
