Places I have dealt with would accept a doctor's approval for diving if it's within 1 year old. So, get an annual physical and get your doctor to sign off on a scuba form (if you have any reason to mark Yes on a regular scuba medical questionnaire).
I think the medical for my SDI pro card required a doctor to sign off within the last year, regardless of whether there was a Yes on my questionnaire.
