That really does sound like the ages that people would use on interstellar space stations. I may use that from now on.

In other news, I reprogrammed the song on my doorbell in honor of my 20K birthday. It was rather difficult because unbeknownst to me, the batteries had died and corroded the contacts. So it took some work up on the stepladder to get it working again. But I found a great ten-second clip of Pete Townsend singing, "Let My Love Open The Door".

Did you account for the fact that the first seven days after creation were likely inordinately long?
