Ask HN: Is "At which age did you start coding?” a good data point for hiring?

Was talking to someone I trust who told me this is a question that gives a solid data point on a candidate developer's hire-ability, with two qualifiers: 1/ Asked from young-ish developers, so the expected answer is always less than 18. 2/ Asked in addition to coding/system-design questions. Has anyone seen a study or even an anecdote on correlation between success of a developer if they started coding earlier (say 11yr), rather than later (say 15yr or 16yr) in their youth?
