What's the closest you've ever come to dying?

[TruckOSaurus]

I don't think I've ever came close to dying but my young brother did... by my fault. I was working on a little wood camp when I was about 14, it was very high up (like over 4 meters high).

After hammering some nails on the roof, in a stupid move I decided that the hammer would get down faster if I just let it fall to the ground. My little brother (4 years old) was running around the camp, the hammer fell right in front of him, inches away from crushing his skull.

I've never felt so bad in my life!
