    【Question】
    Please list the top three patients' birthdays with the highest glutamic pylvic transaminase in the normal range. highest glutamic pylvic transaminase in the normal range refers to MAX(GPT < 60);

    【Evidence】
    highest glutamic pylvic transaminase in the normal range refers to MAX(GPT < 60);

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT T1.Birthday FROM Patient AS T1 INNER JOIN Laboratory AS T2 ON T1.ID = T2.ID WHERE T2.GPT < 60 ORDER BY T2.GPT DESC LIMIT 3
