What is the most popular object in the world?

Answer 1

Doors

Though doors seem to take little importance in our lives, they're more vital to us then our everyday cup of coffee. With several uses and many types, doors turn out to be the number one most used object today.

Other doors, like the ones on closets, are made to hold storage without letting it leave it's given place. A door frame is also the best place to hide while in an earthquake.

First, there would be less privacy and safety of valuables. Second, There would be no point in building structures, for there would be no limit to what comes in and out, anyone could enter. And since doors make living in structures possible, without them people would most likely live in the mountains or caves.

They are much weaker than doors and provide minimum protection. Even the bullet-proof glass does not provide as much protection as they say it does. A 50 caliber rifle can easily penetrate it, while some doors can resist bomb blasts.

The simplicity of doors is great, but the jobs they have are not. No object on earth has as many occupations as a basic door. And even though other objects may seem more important to you, the door will
