Why does time (seem?) to speed up when we are happy?

Einstein's relativity theory. He explains it as such

>When a man sits with a pretty girl for an hour, it seems like a minute. But let him sit on a hot stove for a minute and it's longer than any hour. That's relativity.


Relativity says that as an object goes faster, the more globally bent timespace is round it, which means, clocks go slower.  Now you may wonder what this has to do with you...well, you're a clock. When our processes go slower, time seem to go faster for us. 

Basically, what you're experiencing is a taste of nonexistence. And it taste good.



Or, it could be as simple as you enjoy the subject at hand so you're not worried about what time it is, whilst when you're doing something boring part of you is wondering how long it will take.
