A woman in Chhattisgarh has apparently been drinking just tea for the last 33 years and is not only alive but completely healthy.Pilli Devi-known as 'chai wali chachi'-from Baradiya village in Koriya district gave up food at 11 and has been surviving on tea ever since, said her family. Pilli's father, Rati Ram, said the 44-year-old quit food suddenly in Std VI. He said she initially took biscuits and bread with milk tea, but gradually switched to black tea , which she consumes once a day after sunset. Pilli's brother, Bihari Lal Rajvade , said the family had sought medical advice to ascertain if she was suffering from any disease, but doctors couldn't diagnose any health issue behind her behaviour.Dr SK Gupta from the district hospital, however, said it is not possible for humans to survive on just tea. "Scientifically speaking, it's not possible. " Agencies
