Started smoking at about 12 or 13 years old back in 1979 under typical peer pressure.
Met my wife and subsequently her grandfather who was retired Navy and Customs and had smoked since he was a teenager as well. I became very fond of him, outdoorsy, a hunter, woodcutter, a VERY hard working man.
I watched him go from a seemingly healthy man, to dying on June 1, 1995 at the age of 71 in about 1 1/2 months from congestive heart and lung failure.
I quit cold turkey on July 25, 1995 after seeing that.
