The 131-year-old man is believed to be the oldest human alive in Uganda. It was his dying wish to meet Y.K Museveni ... and his wish was granted after the prez read about his story in the newspapers.

He was instantly invited to meet face to face at State House in Entebbe.

John Ahumura, who requested that the government help build him a house and take care of his needs, got his request granted ... everything will be taken care of ... thanks to the prez's kindly generous disposition.

John was born in 1885, according to his birth certificate.
