Ah the immortal "Old Man Smell" debate, I would only add that most truly old men that I ever encountered smelled of cheap cigars or pipe tobacco, stale beer and the farts thereof.

Now that I'm approaching codgerdom myself, I would only offer the following advice to the original poster:

Wear what you like, the only person you really have to impress is SWMBO and generally speaking unless you smell really bad she won't say much. If this is the case (at least in my house) you've passed the smell check for the day. If she remarks that you smell nice, remember what you're wearing and continue to wear it.

I agree that most of the modern metrosexual crap smells like woman's cologne on a man. Although Acqua Di Gio and Cool Water are not so girly and seem to play well with Aqua Velva Classic.

I think you'll find that most of us here are Clubman, Bay Rum, Aqua Velva, Old Spice guys and there's certainly nothing wrong with any of those. I also dabble in things like English Leather, British Stering, Jovan Musk, etc. But yeah, at the end of the day, wear what you like.
