Wait... this is the end?

There was a cartoon a while back where somebody explained how a person's life is like the sands in an hourglass. When you're young, there's a lot of sand so it appears to be barely moving. But as you get older and the sands run out, it seems to run quicker and quicker even though it's always been falling at the same speed.

I guess my sands are starting to run out because it seems like Christmas was just yesterday.
