We are human beings
Humans are the animals that cross the nature and do extra things .
If we relate ourselves to other animals we'll see that our only work is surviving and reproducing to prevent our extinction but as we all know we do lot of extra things and in these extra things we created the world of internet where our other self exist where we can be anything or anyone and here we are only the mind and not the body we all are virtual here.
So we are body+brain in real life and we are only brain on the internet and the problem is we are giving importance to our internet life more so we are becoming just brain and we are creating most of things for the Muse of our brain like movies, music, virtual games or worlds just for the brain.
So we can say we are becoming more of the brain now a days.
