Aymara Indian Carmelo Flores (R) and his son Cecilio joke during a Reuters TV interview in his hometown of Frasquia, 110km (68 miles) north of La Paz, on August 16.

According to Flores' identification card, he was born in 1890 and celebrated his 123rd birthday last month, making him the world's oldest man.

Flores, who used to work as a farmer, has lived next to Bolivia's highest mountain, the Illampu, for his entire life. He eats what can hunt, like snake, lizard and fox, only drinks mountain spring water, chews coca leaves, avoids sugar and says that he has never been seriously ill. Reuters/David Mercado
