How long can you survive without food and water ,5 or 7 days maximum ? But Prahlad Jani a holy man from India has been able to sustain himself for the past 70 years on breath alone without food and water . Prahlad Jani claims that he is living as a monk since he was 7 year old and he was blessed by a Goddess.

India's Defense Research Development Organization (DRDO) are running tests in an attempt to understand how a man aged 82, Prahlad Jani, has been able to sustain himself for the past 70 years on breath alone to develop enhanced survival techniques. Currently Prahlad is being closely monitored by the Indian defence force. It has been more than a week now and there is no sign of thirst or hunger in fact there is no sign of physiology changes at all. Jani claim he gets the energy by meditating. Jani is monitored 24x7 with video camera in his room and a mobile camera that follows Jani when he moves outside. 

Prahlad Jani brain is currently working like that of a 25 year old man due to his yoga practice. Dr. Sudhir Shah, a neurophysician involved in the study, called this a miracle in the science.
