i often consider myself a night owl in that i am rarely asleep before 10pm and usually between 11pm and midnight and my alarm dog wakes me around 5am.
i often lose myself in youtube and while doing something in my office space so time disappears. it does annoy my wife though who goes to bed around 8:30pm and gets up around 8am. by 8am i have usually walked the dog for 90 mins and showered and changed and be at work in my office for at least an hr by then. plus i never have any trouble falling asleep whenever i want to. i always sleep on planes and ferries, get on sit down and go to sleep. wake up on landing or docking. takes me about 5 seconds to fall asleep at night. wife starts to talk to me when she has trouble sleeping and then goes "oh you bastard you are asleep already" which she tells me in the morning LOL. i am however not as bad as i used to be in that i used to barely get more than 3 hrs sleep a night. must be age catching up to me
