#3: Every Tennis Racket Is Unique
I don’t know about you, but I tend to assume that everything is made by machine these days. There are amazing machines out there that can manufacture all sorts of complicated products, so I always think that there’s very little that’s actually made by hand anymore.

But some things still are handmade. For instance, did you know this interesting fact about tennis rackets? Personally, I think it sounds like incredibly tedious work; the people who do it might wish there were machines for it. But it’s cool to think that some things are still done by hand.
