I picked up the pipe at 34 and have been puffing for about four years now. I was worried my wife might feel it was old man-ish, but as it turns out, she thinks it is really nice. She bought me my two nicest pipes and a pipe rack. When we travel, she enjoys visiting B&M shops with me. My early teen sons both think my pipe smoking is very "cool" too. I've always been a heavy reader, lover of good conversation, philosophy, theology and the outdoors. I also pick the guitar and mandolin and play a little irish whistle. My family says the pipe fits my personality perfectly. The only conflict I have had is that my family, my friends and I are all fitness enthusiasts, and the smoking stigma is hard to shake, even though pipe smoking, if done sans inhaling and in moderation, is far different from cigarettes. My circle of friends and family all know I smoke a pipe now, after a few years of coming my out of the closet with it. I have a couple friends who, when the time allows, want to try a pipe with me.
I think the "old man" image just stems from the fact that the fellas who thrived in the glory days of pipe smoking are now in their latter years.
May God bless pipe smoking. May it lead to much contemplation, good conversation and a willingness to just slow down a bit now and then.
