Its actually anatomically easier to vocalize more quickly with a higher pitch, because higher pitched soundwaves are shorter and thus can be faster. So maybe he wanted to deviate from his regularly (slightly) higher voice and see how it sounded? Probably not, but possibly.
Just an opinion but for my money (and remember; the pound is stronger than the dollar ) they are better than anyone I've heard from KC besides Tech (including the Strange artists) and everyone who was featured on Killer besides Scarface.
The lead singer of the Offspring was actually planning on doing that and calling it "Chinese Democracy: You Snooze You Lose" but later backed out saying it was a April Fool's joke.
actually not entirely, brotha lynch had season of siccness... so i was kinda takin a bit of that. and since tech already stated "sickology".. i just played off the Sick part.
You could take the 101 a different direction...
Intro to Sickology or Introduction to Sickology
or even Basic Sickology. 101 just seems cheesy to me cuz of Jeezy's cd.
