Why does time seem to go by fast when you are having a good time

Question

I know it doesn't but how come it seems to? At work, time goes, again seems, to go by very slow. But then you're in your own time or out with friends and an hour seems to be like a minute. Why is this?

Answer 1

Emotion and time are interrelated,all feelings are the produce of that interaction.Sexual happiness lies neither in the female nor in male  but in interactive principle.So also the time related emotions.

Answer 2

Because at work you're hoping to get out of there as soon as possible and when you're having fun, you don't look at the clock often and you're not aware of the time. When you're having fun, you don't want the fun to end; or you at least don't have any intentions on wanting to leave soon.

Answer 3

Speed is relative to mind. Good time looses your awareness. Slows the time in your mind. The way out from reality.

Answer 4

it's because you're not so focused on the time and instead focused on the activity. this substitutes the time and makes it seem like it's going by fast
