What is the most risky thing your have ever done?

[Haarek]

Probably going down a very steep and long hill in my residential area with no visibility of the road ahead (which was extremely narrow, only one car at a time could go around). I was doing this on my motorbike at around 100/120kmh with only one of my brakes working. Luckily no cars were coming otherwise I'd be pretty much dead.

Or maybe when I tied a rope to my best friends bicycle on my motorbike and dragged him through 3 different towns at full speed overtaking every car and avoiding oncoming traffic. All of this with him wearing swimming shorts, flip flops, a T shirt and no helmet. Though this probably was HIS most risky thing instead of mine, it was pretty risky that I could have easily killed my best friend.

That is actually pretty insane, why would you do that in the first place??
