Wondering what it takes to be a pro golfer? Well, more than anything else, this picture tells the story.

It takes blood and sweat, and thousands upon thousands of golf balls bit over the course of many years. Of course, that takes a toll on players’ hands — especially the ones that don’t moisturize appropriately. Don’t believe me? Look no further than Alex Noren’s hands. The picture was snapped a few weeks ago, but the European Tour’s official account is brining it to light for people who may have missed it the first time.
