This is something I recall as a child waiting for the bus in Key West Florida; but haven't done for as long as I can now remember at this point in my life.
June first brings us Flip a Coin Day — which is a day for making decisions with the ease of flipping a coin.
Now then, the tradition is said to date back to the time of Julius Caesar. It is said that Caesar would take a coin and flip it to make decisions where the correct choice was unclear.
Ideally the correct answer was "heads", which of course carried his image on the coin.
Et tu, Brute?
In our day of lotteries and other games of chance the flipping of a coin has become irrelevant in my existence. Therefore I will likely allow the day to pass without needing to participate.
Though I don't find the practice efficacious in my personal decision making, by all means, should you find yourself so inclined I think you should go for it !
