What most people reading this is suffering from ''Boredom"
This infection is easy to but hard to cure. This infection can be caused by simply a teacher teaching something
you already know or by your lack of tv show recorded or by simply binge watching Bobs Burgers.
The only cure is by doing something mildly
interesting like counting the nails on a wall or by
playing around with siri (Or cortana if you have an Microsoft phone)
But sadly there is no medical cure so instead of being bored on your ass all day go for a job and be productive.
