Question: Which year recorded the most number of goals by a player and how old was the player at the time the most number of goals was achieved by him?
SQL: SELECT T1.year, T1.year - T2.birthYear FROM Scoring AS T1 INNER JOIN Master AS T2 ON T1.playerID = T2.playerID GROUP BY T1.year, T1.year - T2.birthYear ORDER BY SUM(T1.G) DESC LIMIT 1
