Am I A Mutation?

I was browsing through a skydiving website that I used to frequent back when I was an avid skydiver and saw the company who owns it is listed as D4DR Media. I clicked on the link and saw the following statement on their site:

"If you have a mutated D4DR gene, chances are we'll meet you on one of our sites."

Considering all the different activities that I thoroughly enjoy (flying, skydiving, skiing/snowboarding, downhill mountain biking, etc), I think I may be afflicted with this "disease". At least now I know it's not ALL my fault.
