In 73 I wanted to do something to give me an edge playing sports.....My dad told me about a friend of his who did the same thing....for a year they hardly saw him....then all of a sudden he was stronger and faster....could hit a baseball a country mile...so I met him...he was really a great guy...he and his wife were longtime friends of ours and still are to this day....

Only need one word for the ?........CHALLENGE
