I think someone has proposed a formula according to which we experience the passage of time as a function of age. So basically time passes faster the older we get, I guess the reason would be that there's less and less fundamentally new things to experience and hence less lasting memories. I saw it in a numberphile video, but don't remember which one unfortunately.
