Ghandi didnt live off hose. He ate like a typical person, but when things be going wrong in society he would almost starve himslef so individuals would pay attention to his robustness, rather than associates fighting eachother almost stupid things.
I think 3 weeks.
a month or two.
6 months
ghandi have nothing but river and green veggies. that gives vitamins and fiber, so on... not sure exactly how long someone can live resembling that though...
