Tom,
 

After spending some time in the healthcare domain, I've noticed that in the context of patient care - exact age isn't really that important. I mean, does it really matter if the patient was born Jan 29, or Jan 30? Or even Jan/Feb/March?  

 Most of the time, the answer is no - unless we're talking about newborns or infants.
 

 The age-group has greater significance than the age: newborn, infant, child, teen, adult, senior, etc. 

 I'd suggest spending some more time with domain experts to analyze the kinds of rules that would be written.
