Maybe he hasnt eaten in a long time, that long time to him = 70 years. Sometimes i say i havent eaten in 10 years but really i mean 3hours
Have seen documentary on some young girl who had a disorder where she couldn't eat. She drank water all the time.
you guys are forgetting one thing..the doctor! hes getting fund for his research! its all about money.
I don't think it's really possible to have no food or drink in 70 years, how does in get his energy from to stay alive
