Last Thursday of June, people across the nation observe National Handshake Day. Of all the various forms of greeting, the handshake is perhaps one of the most ancient, a non verbal mode of communication, it may have existed before written records. Shake the hand of at least one person that you would not have on any other day & wish them a good day while doing so. It’s also a day to perfect your handshake. New Normal: Elbow bumps to avoid hand and skin contact to stop the spread is proper.
