The following photos are of Hanuman Das Baba of Vrindavan, who may be one of the oldest living saints on earth. Once I asked this Baba how old he was. He Replied he could not remember his age, but recalled that he was 12 years old when Jhansi Rani fought the British. You can deduce his age from that. Jhansi Rani fought the British in 1857, so he would be around 170 years old.
