It's hard to take advantage of the spring time tame.. what can you do with a lost hour of time?
But in the fall, you have a chance to live a single hour twice! This is generally discouraged by the powers that be, since they put this at a time when most people are unconscious, but think of all the things you could do in two hours and claim it was all done within an hour!
Let's say you can run at a speed of 5mph. People wouldn't be very impressed if you told them you ran 5 miles, but if you told them that you ran 10 miles between 1am and 2am, well, that sounds a bit more impressive.
I imagine that flights are the most impressive when it comes to this speed/time ratio. Think how far you could get flying for an hour only to end up somewhere at the same time you left… ooh, what if you crossed a timezone and went backwards and additional hour?! Crazy!
Ok, these are pretty lame. There's gotta be a better way to utilize this phantom hour. Ideas?
