The idea of time going faster as you get older is an old idea, but it seems quite valid to me. I no longer complain about those really old guys with hats creeping down the freeway in front of me, since they probably see the highway going past a lot faster than I do.

While you can't do much about actually travelling in time, it would be cool if you could adjust your brain to slow or speed up your perceptions of time passing. Sitting waiting in an airport? Crank it up a bit and watch the clock hands whirl around. Drop a fragile vase? Slow it down a bit and catch it like Spider Man (assuming you can move your hand fast enough...it would be like swimming in molasses.) Time flies when you're having fun. If you could harness the effect...
