This story stuck out to me today, for a couple of reasons. http://money.blogs.time.com/2011/03/11/the-frothy-fast-giving-up-food-but-not...

I have a feeling that if the monks of the 1600s broke their fast on Sundays, they didn't break it with anything too substantive. They probably just pulled out their blender and threw together a yummy smoothie of some kind.

Whoah, news flash...17th century monks had blenders? How cool. I wonder how they kept them secret from everyone else until the 1920's? ;)

Two days in, Wilson awoke with headaches.

Perhaps Mr. Wilson is normally a coffee or caffeinated soda drinker when not observing his frosty lenten fast. The story neglects to elaborate in detail his "normal" consumption habits. Quitting caffeine cold turkey can lead to serious physical side effects, like headaches. It could also be that he's drinking the wrong beer. Who hasn't had some headache inducing batch of liquid bread in their day?

Reagardless of the facts in this case ,you can get more insight into this guys "adventure" at his blog. http://diaryofaparttimemonk.wordpress.com/
