>Time is going by very fast. Hours are changing like minutes. Why is it like this?
I have a couple of theories

The first is that as u age and experience the same things over and over, ur brain "switches off" and doesn't bother committing details to memory - kinda like a compression algorithm. This causes the time u just spent to seem like it skipped forward. It's only when you're experiencing something new that time seems to pass slowly (well, that and staring at a clock), since ur brain is hyperactive and recording every detail

The second is how we compare periods of time against our entire lifetime. For a 10yo, 5 years is half their life; for a 50yo, 5 years is only a tenth. The 10yo perceives 1 year the same way the 50yo perceives 5 years; the 50yo perceives 1 year the same way the 10yo perceives 0.2 years
