ive done quite a few stupid things in the short time that i have been on this earth.
the most blatant one would be one of the first times i got drunk somewhere around 14 i think? anyway we were camping and had just built a large fire. I picked up a nice round rock and threw it into the fire, and then decided i shouldnt of done that and i wanted my rock back. So i stuck my hand in there and brushed the metal firepit container with my wrist which was pretty close to red hot at the time.
Worst of all the scar i hoped for after everything was all said and done faded after a couple months
I have also done many walks through bonfires on the burning logs and stuff. All good fun
