is there something that hinder your life ?

Disintegrating bones.

Pain, degeneration in my neck, arthritis, trapped in a body that will not operate to my will. 

Yes, understandably you are afraid of the stigma that comes with having a criminal record, if you are a different person to what you was then, then give yourself a break, I'm sure someone else will.  Everyone changes, I'm not the same person now, as I was in my twenties, or thirties, as people grow up and experience life they usually become a lot wiser, don't allow yourself to be trapped in the past or you won't be able to move forward and grasp new opportunities.

Seems to me there's more to your story that you're not telling.

A few relatively little things, nothing too serious.

Arthur. I played a lot of rough sports in my youth, I'm paying for it now.

Don't we all have something?  We are human so subject to our appetites even when we try not to be. We want it all but have to settle for as much as possible and even then we are making choices, weighing,  and making trade-offs. 

Not really.

I've accepted that I will have to do work I really don't want to do - thousands of hours of weeding and aged care for at least ten years - in order to make ends meet.
