Brett & Kate McKay bring us a list of 15 smells that are associated with Manliness. I don't know about the bowling alley, and I never knew my grandfathers, but the rest is spot-on.
I think I might consider adding the smell of a working automotive garage, with axle grease, solvent, and fresh tires. Oh, and an old-style tire store. I think also that I associate the mixed smells of gasoline and broken earth, perhaps with perspiration, as a manly smell.
Now, I know that some will protest that there's nothing inherently masculine about sawdust or shooting, or gasoline and broken earth or the like. That's certainly true. My wife the sculptor uses our table saw as much or more than me, and can weld (another manly smell?), while I can't. She mows our lawn as well, and I shoot with too many women to count.
But I associate some of these smells with men of my youth, and I can't ever release that. As long as I don't treat women inappropriately because of my associations, I believe that I can accept that about myself.
