GenX - here's a few:
Lawn darts. Unsupervised play over 1/4 mile from home at age 8. Unsupervised play over 1/2 mile from home at age 10 with a BB gun. BB guns as paintball weapons. (no eyes were put out). Riding a bicycle to school on a highway shoulder from grade 7-9. Latchkey kid. Going fishing with a neighbor (retired man) as an adolescent for 2-2 summers. (Ps. We fished and talked.)
Seems like a guillotine would be far more humane. No 80 seconds of breathing - man that must be like an eternity of pain.
