When I was 4, a bull charged at me but I got picked up from over the fence and it slammed into the fence instead. I remember the guy falling us back into cow poo and I got upset by this. I did not know a bull got out and was charging me.
I went off a cliff on a motorcycle. I was in a mountainous area and low-sided on a turn, going under the barrier and off the mountainside. I got caught in a tree 12m down and the bike was located 70m down. I only broke a few bones but one was the femur.
I had my board leash snap surfing a cyclonic swell (about 12–14ft day). As we used a riptide to get out faster, it was hard to swim in and the waves were so big I couldn't swim out. I was being sucked out and dragged in, stuck in the breakzone for about 20 mins until I was so exhausted, I had to choose to swim north and hit a rock shelf. Surprisingly, I didn't get cut up and eventually the rocks protected me from swell. I could dive down and hold onto them as sets would roll over. I collapsed by the time I got out and took about 30 mins to recover. I threw up a lot and almost blacked out a few times.
Recently I was almost t-boned by someone running a red. They were doing about 90kph and did not slow down at all. I thought they were driving suspiciously fast for a red so braked enough to miss them ahead of time.
I can't think of a fifth, but I do a lot of extreme sports and outdoor adventuring. There has been a lot of high-risk situations but have always been in control, putting safety first and being well prepared.
