Tips for Ageing Golfers [EPUB ebook] 
(Adapting Your Game to the Passage of Years)

The author has played golf for over fifty years, played to scratch, won the club championship at golf clubs in two different countries, and had a best-ever round of 64 on a par 72 course in America. He would be best classed as a pretty good amateur golfer.
Because of ageing, he had to undergo several operations, which made him realize that his golf swing was going to have to change. That realization started a new learning phase that lasted several years, and his findings are presented as tips for ageing golfers. At the age of 74, he shot his age and has done so every year since. He is now 82. All ageing golfers would benefit from reading his booklet Tips for Ageing Golfers.
