A 60 year old career instructor asked me recently if it would be possible to pass PSIA Level 3 Certification. The person passed Level 2 competently several years ago, has taught extensively since then, has lost a significant amount of weight and is in better shape than at the L2 exam, but was 45 then too. The person's big concern is the ability to ski more difficult runs without interruption of flow. I would say this person is a technically proficient skier who has worked really hard on Skiing Right but has shied away from situations that might require hanging it out there, so to speak, which is understandable in a 60 year old skier, but maybe is not conducive to achieving Level 3.
I am sure all you instructors know someone like my friend. What would your advice be if asked a similar question?
