Your favorite piece of technology

If you think on a piece of technology inmediatly comes on your mind aa thousand of things like cell phones, smartphones, play station, xbox, cars, smart TVs or computers. But I think in other things, gadgets that the entire world use every day and now live in a complete oblivion. I'm talking about an instrument who have a vital importance in our lifes, but admit it it's embarassing for the people, that gadget, it's the higienic paper, yes the higienic paper, it's simple, useful for many purposes, all people have used it almost one time at the week.

I cannot imagine a world without the higienic paper, we all need the higienic paper, is a basic and very important piece of our lifes, if this magic paper doesn't exist we have to clean our asses with vine leafs? nettle leafs? sandpaper? I dont think so, just imagine what you will do in a world without it. When you go to the toilet and there's no sign of paper in the room, your heart begins to acelerate and thousands of thoughts about what you have to do in that moment comes around your head, a sacrifice is required, your hand? your clothes? a stocking? This is when the higienic paper comes to our minds and to our hearts, are you still thinking the higienic paper is a bad gadget? I'm not sure  about that, for me, the higienic paper is a vital piece of technology.
