Hmmm… Time IS relative to the specific object, so one theoretically could live a slower lifestyle to make the time stretch. However, it seems the mere sum of revolutions around the sun that one does (years lived) will dictate at least some perceived speed of passing time. You raise a good point, though. We talk about living a slower-paced life and boredom making time seem to stretch. Being bored may really have that effect for individuals.
I can’t help but mention time dilation, which I know nearly noting about other than massive gravity can cause it. @Polar-Bear you should start the space-time thread!
