86,325

What's really sad are those days when you yawn just right and the day then seems like its only 86,399 seconds long instead of 86,400.

Bummer.

Then you accidentally discover that the government picked that day to be only 86,399 seconds long anyway. So that means the day really only felt like it was 86,398 seconds long.

Bummer.

Then you realize you've just wasted 73 seconds reading somebody's Yawn Plus Atomic Clock Government Conspiracy Theory Nonsense, so that whittles it down to 86,325.

Bummer.

Of course when you are an eternal being like myself none of this really matters at all.

Update:

While walking in the park this afternoon I came up with this interesting option: If you could sleep 18 hours a day, be awake for 6, and this would allow you to live for 200 years in relatively good health, would you do it?
