One is years ago I had an accent where I actually fell off a roof and I'd been training my neck at that time for a sport that I was involved in and I walked away from it with a sore neck but not a broken neck. I was once in a car accident where I was parked... and someone rammed into us at full speed. [...] But I think one of the reasons why I was able to essentially walk away from that, I didn't have any sustained damage was because I trained my neck.
