I was fifteen at the time and I was trying to start a fire for a braai when I accidentally touch the fire, I flinch expecting pain, but nothing came. I checked my finger and realize not only was there no pain but there was no wound. I was shocked to see this and thought maybe I was dreaming but I knew I wasn't. I kept testing it until I shoved my whole hand into the fire but no matter what it didn't hurt me and only provided a gentle warmth, I was flustered and decided to keep testing this strange ability whenever I could. After a year of testing, I learned that so long as what is hurting is a force of nature it won't do any damage to me and, realizing this, I decided to become a firefighter since the fire won't hurt me.
