A 22-year-old UK man is dead, and a quote from the local assistant coroner sums up the sad and bizarre tale: "While in the kitchen, he took hold a knife to demonstrate it was stab-proof and sadly realized it wasn't the case." Authorities in Teesside say that Jordan Easton was at a friend's house and boasting to others about how the vest he was wearing could withstand a stabbing attack, reports Teesside Live. He then stabbed himself in the chest, fatally, reports the Independent. After an inquest into the death, authorities ruled the injuries to be self-inflicted, though unintentional. Assistant coroner Karin Welsh chalked it up to the "foolishness of youth." (More knife stories.)
