MY FAVOURITE PIECE OF TECHNOLOGY

Just like N. Tesla used to say... Hi everyone.
I don't know how to approach this topic, because I understand that all the objects that humanity has created can be considered as technology. Taking this into consideration I wouldn't know which one to choose as my favorite, because I like to wear clothes, but I also like to be able to shower every day and not do my needs in a hole...
Anyway, to make my job easier I'll just say that my favorite piece of technology is the cell phone, I don't really remember when I had my first cell phone. It's something I use every day and almost all day, I always carry it in my pocket, now that I think about it the pockets are also a very important invention for me.

I use my cell phone for many things, it's my watch, my alarm so I can wake up in the morning, I use it as a notepad, to play video games, to place myself in the calendar, to read books, to watch documentaries and conferences, to receive information about the university, to communicate with people who are not near, and during these days to have classes.

I imagine that life without a cell phone would be almost as it already is, only replacing the functions of the cell phone with objects that serve the same purpose.
