For most of us, golf is a game we think of as something we'll always be able to play.
If you've been at it for any length of time, you probably went through a period where you were hitting the ball further than ever without doing a thing other than buying better equipment.
Of course, the vast majority of people reading this never played the game competitively. At best, maybe you've competed in your club championship. If you have any years on you, you've probably dropped down a flight or two or signed up for an age-classified competition.
Professional golfers don't have that luxury before they've reached the age of 50 and may opt for the Champions Tour.
For most, their 40's are a kind of limbo. Can't quite hang with the young guns and can't go play with the old farts. Yeah, yeah, I know, "50 is the new 30." Maybe in some things, but even a driver with a head the size of a boxing speed bag can't make up for a decline in most everything that's grippin' and rippin' that club.
Then there are a handful of guys who've managed to defy the aging process. Or, at the very least, delay it long enough to still win regular tour events, maybe even a major.
