You know the drill… Traveling through an airport yet again, with your backpack on and rolling 1-2 bags behind you.

Probably not our most fun moments, all things considered.

But remember this: Not long ago, suitcases didn’t have wheels. Look at photos of people in Ellis Island, and they’re all holding giant bags in their hands, like suckers!

With the wheel being one of humankind’s most primitive inventions, it’s hard to believe that we were that dumb for that long.

No one thought to put a wheel on bags for thousands of years, until 1970?

We like to believe that every good idea has already been done before. But rest assured, every day we are doing things that future generations will look on as incomprehensibly stupid.
