Hi Jim, thanks for responding and I get your point. I think you can guess that I am clutching at straws. I just wondered if there would be an outside chance of triggering a eureka moment in someone. I would say I’ll leave it to the doctors to fathom out, but they are scratching their heads as much as me but probably not as worried about LC as they can take a more objective view on potential causes and their likelihoods. Take Care, Aaron.
