I flew from NY to Hong Kong direct, you kind of understand why people used to get that "air rage". My mate decided he would track me when I was in the air, he saw me take off, he went to sleep, woke up, checked where I was ("you moved like 2 inches ffs"), went to work, came home, checked again ("ok, bit more than halfway there"), had dinner with family watched TV and noticed I had landed just before he went back to sleep.
He asked what I did, replied "watched three 2 hour movies, 4 blocks of television shows(hour each), slept for 6 hours and I still had like 6 hours to go".
