This Age Observation represents the subject's age at onset of an event or observation.
The age of a relative in a Family History Observation at the time of that observation
could also be inferred by comparing RelatedSubject/subject/birthTime with Observation/effectiveTime.
However, a common scenario is that a patient will know the age of a relative when
the relative
had a certain condition or when the relative died, but will not know the actual year
(e.g., "grandpa died of a heart attack at the age of 50"). Often times, neither precise
dates nor ages are known (e.g., "cousin died of congenital heart disease as an infant").
