@OP... From an old fat bald guy that has been around the block a few times... If it is something that you truly want to do, and your spouse approves, Just Do It...
I chased a dream 15 years ago. Was not successful at it. But gave it my best shot. If I had waited until I retired to give it a whirl, I would not have physically been able to do it. Tomorrow is promised to no one.
