Ben hogans five lessons | Golf Monthly

I bought his book The Modern Fundamentals way back in the 1980's and it was dated then.
So it's even more dated now with all the equipment changes.
There is no such thing as the correct this or that. It's whatever works. The Vardon grip is probably as good as has been found, though.
Hogan also had a secret which he didn't publish until offered money from a magazine.
Again, it turned out to be misleading and one expert commented it could even destroy your swing.
In the end, like so many, he couldn't do it himself, such as Faldo's Swing for Life.
I'm afraid as you get older your body changes and like the op says the more confusing golf gets.
