An efficient way of unnoticably skipping out on near half of one's life.

Good morning. Am I 53 already..?

sleep 

Something I don't get nearly enough of.

A state in which the body of a person or other mammal is in deep rest. Environmental responsiveness is reduced or even completely lost. This is the period in which the body and mind can recover from the activity of the awake state.

I'm an insomniac, I'd probably be doing a lot better if I was actually able to sleep, instead I'm spending my night on UrbanDictionary.

sleep 

The physical state in which your bodie rests and replenishes it's energy (insomniacs, such as myself, do not often expeirience this, and are reading this definition @ 3:00 in the mourning and need to be awake by 6:00 to get ready for school). Sleep often comes to people in class periods such as math, science, history, P.E., and english.

Last night i didn't sleep for the third night in a row.
