The age is calculated automatically with the birthday, so if the age is wrong someone probably put in the wrong birthday. Also the is no source on the birthday on Mafumafu's page, so yea that one could be wrong.

If you know his birthday, and have a source for it, you can edit the infobox yourself. The fields iirc are 'birthday', 'month', '&year' (yes, with the &; the field w/o the & is a different field), as well as 'ref' for the source.

Hope this helps!
