Question Of The Day: What If We Can Live Without Food?

I wake up on a normal day around 11am and am not bothered about food until around 1pm and i  still don't feel the sting of hunger even as i eventually prepare to eat

   But amazingly i decide to fast today and am awake by 8 only to realise that by 9am am already have a stingy feeling in my lower abdomen and it got me thinking is food just a psychological factor to our existence and can it be possible that we probably might be able to live without food
 
   Like Jesus in the bible who when he went into the wilderness did not eat for 40 days and 40 nights then you wonder how did he do it,or the fact that there have been reports of monks who has gone 100days at times without food nor water.. perhaps you think that is spiritual what of  a stunt man in 2009 who caged himself in a giant balloon in times square, new york city and went 46days without food and water.  
can you?

So is it nearly  possible that eating or food as we know it is just merely psychological, a norm, habit or an addiction that we can probably live without and  that people who have died out of starvation probably died due to the psychological effect hunger had on them and not the actual absence of food

Just saying what do you think?
