The next time you hear a friend complain about not being as fit has he used to be because he just turned 27, introduce him to Japanese footballer and probable vampire Kazuyoshi Miura, who has just signed a professional football contract taking him into his 50s.
Miura, who made his professional debut in 1986 and retired from international football 17 years ago, is the oldest scorer in the history of the Japanese domestic league after breaking his own record last year at the age of 49.
Currently plying his trade for Yokohoma FC in his country's second division, Miura, now in his 32nd season, started his career with Santos in Brazil, and had brief spells in Europe with Genoa and Dinamo Zagreb.
On the subject of his new contract, the vintage striker said: "I hope to keep fighting with all my might together with people involved with the club, my team-mates and supporters who have always given me support."
We'll stop complaining about that tight hamstring from five-a-side...
