My neighbor's weird hobby is growing on me

So my next-door neighbor has been collecting vintage lawn mowers for the past two years. At first I thought it was the most random thing ever - like who needs 15 different mowers from the 1970s?

But yesterday he invited me over to see his "workshop" and honestly... it's kind of fascinating? He knows the entire history of each one, can tell you exactly how the engineering evolved, and some of these things are genuinely beautiful pieces of machinery.

Now I'm wondering if I'm missing out by not having some weird niche obsession of my own.
