Why is it when I was working in an office job, chained to a desk from 8:30 am to 4:30 pm Monday through Friday, a day was so long and a week took forever? At 8:30 I couldn't wait until 4:30 and on Monday morning I couldn't wait until Friday afternoon. And the stretch from one vacation to the next was an eternity.
Now, semi-retired and working (occasionally) from home, the days evaporate like morning dew and the weeks breeze by like a drive in the country.
Moral: If you want a long life, stay in a job you hate.
