XKCD & Insomnia… How did they know?
So for those of you that have never read the comics over at XKCD, a webcomic of romance, sarcasm, math, and language, then you’re in for a real treat…
so I have minor issues sleeping at night, primarily because I tend to work long days and then come home and think and then realize that I need to go to the gym, and end up getting home around 11, the endorphins pumping and I can’t get to sleep. And then I start having times like this comic that XKCD posted on their blag 
So my question is… how did they know that my clock goes to 13:72?
