Today is World Smile Day, a celebration of cheerfulness that was coined and initiated by commercial artist Harvey Ball. Ball from Worcester, Massachusetts, is known to have created the Smiley Face in 1963. He also founded the World Smile Corporation in 1999, which organizes World Smile Day. The day is held on the first Friday of October each year and is dedicated to "good cheer and good works".

It may seem like a stretch but the horrific massacre at Las Vegas, and the destruction caused by Hurricane Irma, Maria and Harvey may have left behind a world which could do with more smiles.
