Enum: AgeUnit¶

The unit the age summaries are in, folded from the source's wording. Closed, because the point of the field is that two studies' ages are comparable, and an open range would put that back where it started.

    description: 'The wording does not say. Distinct from `years`: assuming the common
      case is what makes a misread infant cohort silent.'
