Melanie,
Hi.
How are you?
Smoking cigarette and using drugs are usually only part of the problem.
A person's diet often figures more prominently.
What has your husband been eating as his diet, most of his life, recently, in the last 7 years and during the 18 years before that?
Diet, activity (work and lifestyle), location (for climate) are among many of the factors that can contribute to our condition.
Please give us a bigger picture of his life.
Does he have a first name?
Thank you, very much.
Be well.
Bruce Paine
