Occupational hazard?

Japanese speed eater suffers from arthritis of the jaw.

Takeru Kobayashi, 29, had been aiming for a seventh consecutive win at the annual 4 July US hot dog eating competition on Coney Island, Brooklyn.

But this week Kobayashi, dubbed "Tsunami", said he was in so much pain he could barely open his mouth.

The champion, who only weighs 11st 11lb (75kg), last year ate a then record 53.75 frankfurters in 12 minutes.
