Where has time gone?

Time is just flying by, it makes me kinda sad to see how life changes in an instant...
Once you blink its like another min. of your life is pretty much gone.
The most sicking and saddest part about life and time is that no matter how hard you try you can't take that time back. Its 1:32am right now and thinking about not being able to get 1:31am back kinda freaks me out... but I'd always rather just have a minute forward than a minute back.
