Having introducing this article, a friend of mine who is a teacher in UK responded,
"We talk about developing upper body muscle. Here is another area we should think about!".

A friend of mine who is French introduced me this article a couple of days ago.
She said she reminded me with it. I have been checking TED to make my presentation much better since 7 years ago.
I'm recently somehow sick about what I have been doing so far. However, the article encourages me and has opened me up to think about what I'm gonna do from here on.
