1. My younger brother slipped and fell on the mountaineering route on Mt Whitney and I got in his way to stop his slide. He scooped me up and we rocketed down the icy granite at a fast enough speed to melt his gortex jacket. We could clearly see this was not good and eventually we would start tumbling and die in the rocks below. But my right foot caught a solid four inch cleave in the granite I didn't even see and shot both of us straight up into the air about ten feet. We came straight down and stuck the landing - on our rears. My right leg was broken in several places (pilon fracture) and the ankle dislocated. My brother was unhurt. A guy died on the same chute later that year. He went all the way to the bottom into the rocks
2. Accidentally got sucked over a waterfall in Mexico at age 16. I thought I was dead. Just tumbling over and over in green bubbly water waiting for the impact. I knew there were submerged rocks waiting for me. I actually saw the side of the boulder at the last moment before glancing off of it. I got out of that one with nothing more than a dislocated shoulder on the side of that boulder
3. Swerved to miss an animal crossing on I-80 near Elko, lost control of my car, and rolled it for an eight of a mile according to the highway patrol. The car ended up on its side on the shoulder of oncoming traffic. It was the middle of the night but there were at least two cars nice enough to stop and one who went to Elko to report the wreck. This was before cell phones. All the tires were ripped off and the roof caved in. The first guy on the scene said he expected to find dead bodies. I climbed out of a gap where one of the windows had been without a scratch or even soreness the next day. The car was a Daihatsu Charade which was discontinued in the US partly because Consumer Reports ranked it the most unsafe car. This was a month before leaving on my mission
4. Climbing Kings Peak (Henry Fort-Gunsight Pass route) in the middle of August and got caught 500 feet from the summit in a snow storm. My brother (same as above) had felt altitude sickness and turned around about 15 minutes early before the storm hit. I was just going to sprint to the top and hurry back to catch up to him when visibility dropped to about 50 feet. On the way back, there was a foot of snow where there had been a trail. Visibility was still 50 feet. I had the map and my brother had the compass. I ended up descending into the wrong valley (to the West of Henry Fork). It took me the next 10 hours or so to skirt that mountain range (no trails) to get back to my tent. This probably should be #1 reliving it. The wind peaked at about 50 mph with freezing temps. I was taking huge chances trying to climb down cliffs - literally hanging off the end of a 50 ft piece of rope I had with me at one point and dropping another 10 feet onto a three foot ledge. No return. Nail the landing or go off a cliff and die. It was the most despair I have ever felt in my life. I got back to the tent around midnight. My brother was gone for Search and Rescue. I slept for a bit before packing everything down to the car. I ran into the mounted Search team literally 100 yards up from the parking lot. The sheriff said a man (I remember them saying he was a bishop) died the day before in the storm on the mountain.
5. At about age 13, my friend and I got swept up in a mudslide. It wasn't moving at the time, so we thought we could jump off a fallen redwood tree into the completely liquified mud. We sunk up to our chests and the mud carried us down the mountain slowly (maybe 5 mph) where it was going over a cliff and dropping about 50 feet into the boulder-strewn Laurel Creek (near Soquel-San Jose Rd and Summit Rd where I grew up) bed. I calmly reached over and grabbed the branch of a young tree at the edge of the cliff and grabbed my friend's shirt to keep him from going over. From there we edged our way over and out of the mud. The slide was only maybe 30 yards wide. Not as scary as it sounds, but we were 13 and too stupid to really understand that could have ended differently.
6. Riding down Spanish Fork Canyon on my road bike. I had seen Breaking Away and always thought it would be cool to recreate the scene where he drafted behind the semi. Completely spun out on my top gear, my old Cateye spedometer telling me I was at exactly 50 mph, I ducked behind a passing semi and the draft lifted both wheels off the ground (or at least it felt like it) and yanked me into its wake. The feeling was not what I expected. I don't know how I didn't go down, but that was not fun. I have been de-saddled 4-5 times at over 20 mph on a bike and no big deal. Road rash, etc. This was going to be a different ballgame hitting the pavement in thin biking material at that speed.
7. I thought I could swim across Lake Elsman (also Santa Cruz Mts) with a backpack full of fishing gear. I was 16 and figured if the backpack weighed me down, I would just slip out of it. Well, it did swell up with water quickly to the point I could not get it off. I kept swimming but tired before making it to the other side. I swam/sunk about 15 feet below and landed on the bottom on my hands and knees. I got to my feet and walked up the rise toward the surface still with my backpack on. I was involuntarily sucking in water at this point. I collapsed on the shore and puked and coughed my guts out.
8. At age 7, I climbed about 200 feet up a large redwood tree on our property. I got close enough to the top that it was swaying. On the way down, my foot slipped and I started bouncing off branches. I hit maybe five different branches flipping me this way and that way before getting wrapped around my midsection by one that stopped me. I was definitely hurting after that one.

Those are the ones that stand out. There were others like car surfing at age 16 with my eleven year old brother driving and russian roulette with my Dad's handgun. Not sure why I'm here.
