Hello Mt McKinley, thank you for the response, hobbies are work and aviation. I've done a search as you suggest, can't find any services in my area. I'm sorry only a few of your family understand, having a similar discussion with my Mum. You mentioned diet, I have heard this before, is it just a healthy diet, i.e. fruit, vegetables etc. or is there something special advised? Thank you again for your response, keep in touch, Nige
