You would never know it unless I had shorts on but.
When I was a lot younger and dumber I tried to start a pile of brush on fire with gasoline. That gas vapor is real mean. I had even poured a 20 foot trail of gas to light.
29% of my body got 2nd and 3rd degree burns from the results of that attempt. The explosion was so big it caught my clothes on fire. They told me I would be walking with a limp, because my left leg was burnt so bad. I walk just fine.
Most of the scars have went away with time but the left leg keeps me reminded, of that one dumb move.
