Read it somewhere that as of 2014, the life expectancy in States is 78.6 years. Most people who sleep 8 hours a day would spend 25 years sleeping. I sometimes sleep 12 hours a day when meds knocked me out really bad. Then there are a lot of days when I, like you said, spending time by sitting on the couch in a daze. There are times when I can’t sleep for days though, but I spend it by walking back and forth without a real direction or doing unimportant things while not being 100% focus So yeah, I hear you about lost time. It bothers me so much. I sleep with a desk clock just to hear the ticking voice so I can sense the time when it passes by
