I guess everyone is aware of the hazards of exposure to lead, but I found this interesting. My father attended his college alumni reunion last month. He and the other attendees are in their mid 70's and almost all of their parents have passed on. Dad's roommate was originally from Alton Illinois and his roommate's father worked for Olin in the shot tower. Apparently the years of shotmaking had little affect on the old gentleman's health, he died last summer at the age of 102 from a heart attack.
