Doctors had to free a man from a glass house where he had been living for the past 31 days without food as part of an experiment. He started to show erratic behavior last Tuesday.

Li Zhengjia had conducted a similar experiment previously to see how long he could fast. He was able to fast for 60 days.

Over the past weeks, he has only survived by drinking water.

Li has vowed to go on with his experiment once he recovrs.
