If exists, then assume 2009|8|31|1970|5 and generate age. If does not exist, check if  exists.
 * If exists,
 * If >31 (so cannot be a month), then assume 2009|8|1970|5 and generate age.
 * If not >31 (so must be a month), then assume 2009|8|31|1970 and generate age.
 * If does not exist, check if  exists.
 * If exists, assume 2009|8|1970 and generate age.
