When I was a kid in Brazil in the late '60's early '70's the fireworks industry was virtually unregulated. We used to go to the outdoor markets to get many things and the fireworks stands were there in force for holidays. Almost every man working at those were missing at least one finger. Incredibly it didn't phase my parents so we bought what ever we, as kids, could afford. And that was a lot since we had USD. Fortunately I made it out with all my fingers and toes even after doing some pretty stupid things.
