Question: Name the ID and age of patient with two or more laboratory examinations which show their hematoclit level exceeded the normal range.
Evidence: age = SUBTRACT(year(current_timestamp), year(Birthday)); patient with two or more laboratory examinations refers to COUNT(ID) > 2; hematoclit level exceeded the normal range refers to HCT > = 52;

SQL:
SELECT DISTINCT T1.ID, STRFTIME('%Y', CURRENT_TIMESTAMP) - STRFTIME('%Y', T1.Birthday) FROM Patient AS T1 INNER JOIN Laboratory AS T2 ON T1.ID = T2.ID WHERE T1.ID IN ( SELECT ID FROM Laboratory WHERE HCT >= 52 GROUP BY ID HAVING COUNT(ID) >= 2 )
