I looked up a reply that started talking about how now we have all this acess to information where we use d to have to travel far to learn new things. What we knew was from experince and actually listening to others. This person was also saying that now when asked an interesting question, he/she starts playing with their finger and instinctively pull out their phone. (not always to avoid the question) I find that now when doing apaper even one that requires to reasearch i work better just starting a typing not writing by hand. I found it interesting and true.
my fingers are a part of my brain
