The speed of time

This time will pass. Or so they say. We believe we’re travelling forward, how do we really know? If time changed direction, could we even tell? In days, and weeks, and months like these, time seems to stand still.

...Why is that?

There are lots of theories for why time seems to move at different speeds. Some of them are related to age. Afterall, didn’t time always move much, much more slowly when you were a child? The proportional theory suggests that our perception of time is linked to the constant that is our time alive: “the apparent length of an interval at a given epoch of a man's life is proportional to the total length of the life itself. A child of 10 feels a year as 1/10 of his whole life — a man of 50 as 1/50”, whilst the biological theory proposes that time is linked to our metabolism, which gradually slows down as we age. Or perhaps our heartbeat. Or breathing. Or body temperature. Experiments (some of which are ethically dubious!) seem to back it up; for example, a fever can make you experience time as longer... or is that just because being ill sucks?
