Mustachians end up around other mustachians. I spend much of my time around endurance athletes. So we're running, biking, paddling, and swimming together. And while equipment and race entry fees can be expensive, we've not shopping, driving clown cars, and spending a lot of money on eating/drinking (other than high-quality stuff that fuels our performance). And while some colleagues buy what could be called "clown bikes," they ride them hundreds of miles a month, if not a week, and don't need to belong to gyms, hire personal trainers, etc.
My antimustachian friends -- more like acquaintances -- like to go out to eat and drink a lot, see first-run movies at night, acquire all of the latest electronic gadgets, including TVs and accessories they spend a lot of time watching. Not for me.
