Ill health in sages

Hello Sir'

I read in  many sites including here that practicing brahmacharya gives health and its true. But its true in youngsters or beginners. For the advandced person of any spiritual tradition it  seems it doesnt do much difference. Like the sage Ramana Maharshi suffered the same weaknesses that any other common old person. There was a famous monk Padre Pio who could do many miracles of bilocation but he used a wheelchair because of arthritis and an hernia and was not that old. SUffering illness even from his childhood http://en.wikipedia.org/wiki/Pio_of_Pietrelcina#Poor_health. SO there is change in youngsters but not in advandced practionner, why?
