I always considered myself a nerd (and was proud of it) but this article sums it up quite nicely. Many of your points are very accurate but my friends are more into computers than I am. I also find food to be irrelevant and I only eat because I'm more efficient on a full stomach. Looking back, I also found that I treat things like projects and get the 'High' you were explaining.
The difference, I think, is that, though I love math and science, I also love art (I'm an architecture student).
Also, I multitask everything, like you mentioned in your article. Ever since I can remember, I would read on average 8 books at a time. And whenever I watch TV, my mother always yells at me that I have too many screens in front of me (TV, phone, and laptop).

Anyway, I loved reading your article and I intend to send it to my nerd and non-nerd friends.
