Theory of Subjective Size Perception

Most people have experienced it. You see your school or house again for the first time in ten or twenty years, and everything is so little; the building is small; the rooms are small. It's the same effect when you grow, which you don't. The rest of the world is really getting smaller. This happens more quickly when we are young since then we are having more fun which makes time go faster. Since time is going faster, the world shrinks at a faster pace giving us the illusion that we are growing quickly. When we get older, the days seem to pass hurriedly causing an apparent growth of the midsection. Instead, the clothes, the chairs and the scales' mechanical parts are getting smaller. So to keep clothes and everything else fitting us, don't have fun and don't "grow" old.
