Ex-pro wrestler Bam Bam Bigelow was found dead last Friday. He was 45.

Unfortunately, discovering wrestlers dead at such a relatively young age isn’t even close to being a shock anymore. It’s more of a surprise, say, when a guy like 53-year-old Hulk Hogan appears in a reality TV series with apparent good physical and mental health.

A piece titled “Wrestling’s Dirty Secret” lists dozens of men who died too soon. As does this chart, which includes cause of death. Heart attacks loom over this industry unlike any other.
