Hmm, I got a running start off a 40' cliff and dislocated chest cartilage and broke a rib for the photo.
I've scaled numerous waterfalls with no safety ropes...climbed down (and back up) a 150'+ sheer rock wall. I regularly freedive to 50-55' or so. I was in a deep tide pool with a stormy ocean on the other side of a rock wall with waves coming over the top and crashing into the pool, threatening to take me back out with it. Same trip I got way too close to the ocean and had to hold on to my camera and a rock to avoid getting sucked off the rocks by a rogue wave. I was alone on that trip, it wouldn't have ended well. I've swam into waves that were well overhead and breaking on the beach. Nothing too dangerous, but I guess some of it might be ill advised. Oh, I also gave myself 2nd degree burns the other day, had flaming steel wool go down the back of my shorts. I'll have a couple scars from that.
All the resulting shots can be seen on my Instagram account below in my signature.
