What a lie that we have equal work and play time.  The typical 8 to 5 workday is 9 hours, and that doesn't include time to get ready or commute.  Nor does it acknowledge that some (many) people need more than 8 hours of sleep.  It's all an ugly lie.  Also, if every day is a giant pie, no wonder so many folks stuggle with weight management.  From The Business of Life by A. B. ZuTavern and A. E. Bullock and illustrated by Leo Thiele, 1936.

Climate science hasn't come very far from 1920, when 90% of thermometer readings were inaccurate.  The more things change, the more they're misinterpreted.  From the Bulletin of the Southern California Academy of Sciences, 1920.
