Have you ever looked at something and thought ’What is the point of this?’. Did you know why margins were invented or why doors are made of brass? Do you know what the story is behind those bristles on the escalators (hint: they are not for your shoes.)

Have you ever looked at something and thought “What is the point of this?”. Did you know why margins were invented or why doors are made of brass? Do you know what the story is behind those bristles on the escalators Why do notebooks have margins?

Believe it or not, margins weren’t invented as a guide for writing and note-taking. Margins were invented to protect your work - from rats. Yes, rats. Rats were a common resident in many people’s homes and loved to eat paper and anything else they can get their tiny mouths on. So applying wide margins to paper ensure that the rats chew through the margins first thus protecting the writing.

This can increase the stability of the shoe, decrease impact loading rates, and prevent your foot from moving about if you are climbing or going down a tricky trail during a hike.The brushes on the sides of escalators are not for polishing your shoes. I repeat, they are not for feet. The bristles on the side is a safety feature and is designed to keep you away from standing too close to the sides and the escalator’s skirt panels.Some of us have a nasty habit to chew the caps of pens.

The holes in the pen caps allow people to breathe in case you accidentally swallow and choke on the cap.That drawer under your oven is not for your pots, pans and other kitchen utensils. I know that is hard to believe but it wasn’t designed for that. Manufacturers originally made that drawer for keeping food warm until you were ready to serve it. But we have microwaves now so I guess there is no harm in leaving the pots and pans there.

The “erasing pen” thing came later when it was promoted as such because many didn't understand what it was meant for.Most measuring tapes have a metal stub with a small slot on the end. This is useful for a number of reasons. You can hang the slot on a nail for measurement, if your hands are full and you can also try using the stub to mark the points without a pencil.If you have travelled by plane and you opted for a window seat, you might have noticed the tiny hole in your airplane window.
