Anyways, that makes sense, because when one is tired (a state closer to sleep than being wide awake) one is taking in less oxygen than when one is wide awake, and is therefore holding a greater amound of CO2. __________________ But the solace lay beyond the darkness In a land where light and life dwell Yet soon will come death and the numbing fires Only then will my mind lie to rest For I am alone on this world Enslaved and surrounded by the living dead Yet still I stand tall as I bleed Deep from within the cuts upon my skin
