About 15 years ago (that long already? ;)) I saw a documentary state that scientists had done studies showing that time perception could be manipulated by changing their temperature. The warmer it was, the more slowly time seemed to pass. The colder it was, the faster it seemed to pass. They hypothesized that since people's core body temperature dropped as they age, that it could be a factor in why time seemed to pass faster as we age. For some reason I've always favored this solution.
