In my own personal opinion, the ability to live goes hand in hand with the ability to "feel" the passing of time. Trying to comprehend what death means has lead me to thinking what existing would be like in the absence of time.
Whether or not inanimate objects feel the passing of time or not would lead to an argument of what it means to be alive.
...that time appears to distort depending on you level of personal boredom?
i suggest that your heart-rate increases under stress. i suggest that you heart-rate decreases when you are relaxed. i have found that i view times of high heart rate as passing 'slowly' and times of slow heart rate as 'fast'.
time flies when you're having fun.
a watched kettle never boils.
that sort of thing.
can you have a measure without a scale?
given these points, what do you deduce re: relative time perception?
