    I disagree with your assertion that time speeds up as we age because we are engrossed in what we are doing. As you tend to get older, you actually seem to be less focused on fun activities than you were when you were younger. You're not playing sports, you're not off having fun with friends, you are just doing the mundane. By that theory, younger people would experience time going by faster than older people. Time is perception and the older man at the beginning of the video has an explanation that makes the most sense... which is that our perception of what a year looks like at age 6 is only a 1/6 of our understanding of time over all. When you are 45, your perception of a year is 1/45 which is a very small amount of time compared to 1/6. Your graph on the sum of fractional years doesn't make so much sense to me how your perception of time could be at half overall when you've only experienced 6 out of so many years.

    You must've added the condition that the people must be given room within a short amount of time after they've booked their room. Because, we can tell the persons in the hotel rooms to move to their next room and the previous room could be given to the new customer, but the kick is, for infinite no of people, it is going to take infinite amount of time to get all of them accomodatied in the rooms. But you've solved the previous problem by accomodating them in rooms with odd number. This will take only a finite amount of time.

    One thing I’ve noticed, I’m almost mid 20 years, is life actually seems slower and slower. I haven’t found anyone who agrees, maybe it’s because I attained a traumatic brain injury at 11 years old, but it seems so slow. It also may be because I think so much. Does this happen to anyone else?

    Thinking of it the opposite way. I remember being in a high speed car crash when I was in my teens. When I remember it, its like a long slideshow where every fraction of a second was saved. Can remember every detail even after all these years "even if I can't remember much else ha". I guess when you are younger life's experiences are fresh and it stimulates the brain, it makes the information important and stores it. Its just our perception of time is different to when we are older. I think time seems to go by faster when you are older when you are stuck in the same routine with no new experiences and on top of that memory loss just makes it even worse. Perhaps ditching routines and seeking out new experiences even if we are uncomfortable help to slow things down a bit.

    For the sake of at least proving that the speed is different, could it not be experimented with the idea that maybe it's not instantaneous the other way around? What if the difference is not that big? Consider this: Earth sent a message at 12:00 - Light took 15 minutes to travel to Mars Mars sent a message at 12:10 (assuming the convention and conventional equations) - Light took 5 minutes to get back In this scenario, earth received the message back from Mars at 12:15, but the expected time should have been 12:20, proving that there is in fact a difference in speed, OR, that the speed of light is Distance From Eart and Mars divided by 15 minutes, which is definitely not C. With speed C, light should have taken 20 minutes. We could try this in 4 directions, maybe 8, 32, 64, 128 directions? Relative Up and Down tilt of the apparatus? All we need is for at least one of these directions/tilt configurations to recover a different speed of light so we can be sure that it does vary. Maybe, the variation is different when we're doing it N->S, and the variation of speed between the two journeys would be different when testing for E->W? I know that direction and up and down is all relative (Earth's East today could be universe's North-East in a different time and state of orbit of earth) but it could still be substantial enough that we get a difference? Or maybe we could do 8-10 tests every time the Earth was on the exact same orbit, same spin position, and so on so that variable could be minimized as well?
