Well, I spent a lot of time making this map... I might not be very good at eyecandy, but at least I tried my best.
One of my friends I've known for a long time, and he sometimes has some problems, but he still is really optimistic at times. Then suddenly I didn't see him for about several weeks and when I asked my other friends they told me he was in the hospital because he had a serious disorder, which I never actually knew he had. At times he can't get sleep because of this disorder and he gets extremely sick and tired a lot. I want him to get better so i created this map as a kind of "get well" present.
As for the historical explanation, Ive included it.
