^i learned many things from that expirience. 1.) only 5% of people die from black widows and they're normally infants or the elderly. 2. male black widows are half as toxic but still cause the side effects of labored breathing, sweating, increased heart rate, abdomen/chest cramping. 3. the antidote they give you is called "antivenin" not "antivenom". i didn't stay in the hospital overnight. got the shot, did the whole blood transfer routine, and went home around 2:00 a.m. after getting there at 3. the black widow will leave 2 fang marks from the bite that are exactly(no more, no less) 3mm apart.
