Thanks everyone for your thoughts and suggestions.

His B12 was low 239 ... he has been taking b12 for a few months now. We live in the country so going in to the town pool would be a little inconvenient but within a years time we expect to move to town so will look into it then and a muscle building program too. What we hope to do for a month this winter is go to Florida and we usually rent a house with a pool so that would be a trial time to see if that would be something that he could do.

I think small slow steps is the only way to go otherwise it is too overwhelming and he probabley won't stick to a lifestyle change and end up in the same spot he is now. W farm and he has always put his heart and soul into his work, I tell him he job now it looking after himself.

Thanks again
Nancy
