Edna, we can breathe a sigh of relief that we’ve finally got rid of him, maybe

Bad news for 柯洁 (Kē Jié) (pictured above, left), who apparently lost to the South Korean Lee Sedol (이세돌) (pictured below, centre) the crucial Go match they played today at Haevichi Hotel & Resort in Jeju Island, South Korea. All photos: ORO.

Astrological age

Jeju, South Korea: In South Korea, 45% of the diving women of Jeju are over the age of 70. Ja Kang Song, 71, and Ja Hyun Su, 72, dive for shellfish and are the main breadwinners for their families. Routinely diving to depths of 20m and staying under for an average of two to three minutes, the pressure on the body takes its toll and, like many others, burst eardrums have left Ja Hyun Su deaf. Each season, between seven and 10 women die diving the waters around Jeju Island (제주도). Photo: Andy W. Langton/Age International.
