Curious, Andria, you said your dad smoked 55 years, how old was he when he died and what did he do for a living? My dad died at 77 from MM cancer after a 3 year struggle. The only smoking he ever did was a pipe for a short period of time and a cigar very infrequently. However he spent his life welding rail cars and inhaling all the fumes you find in that environment. His sister, who smoked more than I did but was an elementary school teacher, lived into her mid 80s.
