Time is an interesting quantity. It goes in only one direction. It cannot be turned around or reversed. While its speed in constant (in non-quantum terms anyway), it seems to vary depending on what is happening at the time. Einstein has often been quoted as saying "When a man sits with a pretty girl for an hour, it seems like a minute. But let him sit on a hot stove for a minute and it's longer than any hour. That's relativity."
As we get older, time seems to go quicker. This was brought into focus for me a couple of days ago. We were watching a video of our youngest son's wedding. Our oldest grandson was 10 at the time and he was in the wedding party. He is now twenty. Ten years no longer seems like a long time to me, but when I look at the grandson 10 years ago, and look at him today, there is a lifetime of difference. He has gone from a small child to a full grown adult; needed to be cared for to caring for himself -- and in only ten years. It is amazing how much change can happen to a child in ten years.
Just think what this world could be like if we all changed as much in the next ten years.
