To live 135 years you need Islam, fresh food, mountain air and farming, according to an Iranian who claims to be the oldest person alive.

The Islamic Republic News Agency reported Saturday that Karam Ahmadi, of Kalan village in western Ilam province, is 135 years old and still working his farm.Ahmadi claims never to have taken any modern medication, according to IRNA, which was monitored in Nicosia. The IRNA story was based on a report in the daily Kayhan newspaper.

It said that in addition to farming, Ahmadi still takes his sheep to pasture and collects wood for his winter fuel. He has five children and 65 grandchildren or great-grandchildren.

The Guinness Book of World Records says the oldest authenticated age was that of Shigechiyo Izumi of Asan, Japan, who was 120 years and 237 days old when he died Feb. 21, 1986.
