If you can buy the ticket to the dance.....you should be able to tango your heart out! You come down with fallen arches....that is your problem! Rather than find ways to make things more restrictive.....we need to find ways to make things safer. I would suggest that the industry do just like other areas of endeavour do.....let the insurance companies dictate training standards and set premiums based upon perceived risk. Keep the bureaucrats out of it! Freedom is a wonderful thing.....if you ever have enjoyed it and can understand the benefits of it.
