I recall many years ago that some part of the Olympic games were held near me. There were a lot of tourists for this reason. I remember a news story about an elderly gentleman of 80 years plus was walking with his wife to or from one of the events. They were both tourists here from another country to see the events.
Four young thugs tried to rob them and found out the hard way the old man was a retired and very successful professional heavyweight boxer who still trained professional fighters in his home country.
Witnesses said every time he hit one the thugs they went down and stayed down. The end result was three thugs went to the hospital then jail, one thug ran away and the old man and his wife were untouched.
I just love a story with a happy ending.
