Age might result in neural complexities, but this can apparently be tampered with to some extent. When you watch a movie for the first time, it seems to last longer than when you watch it a second time. It seems to me that as our brain is processing new information our perception of time is dilated. As we grow older, we have to learn less about the world and consequently time is perceived as quicker. I suspect this is why during a drug induced euphoria the experience seems like it can last an eternity and time ceases to exist. Our brain is processing and adapting to the stimuli much as we were doing in our youth. There are of course two different perceptions of time. Current and retrospective. Some days can seem to last forever, but by the end of the week you end up feeling like the week went by very fast. The opposite is true, as well as a mix of both.
