You have a lot more in common with your computer than you may realize

 Your computer has a finite amount of space for storage, processes, power, etc. and so does your brain.
 Pile a bunch of crap on your desktop like worthless apps and programs that you never use and it will run markedly slower. So fill your brain with what your nighbors are doing, Wendy Williams, porn, chatting for sex etc. and you will run markedly slower as well.
