Day 31. Did anyone do more than 40? How much is safe?

Hello,

The book states that in severe cases you are allowed to go even more than 40 days.

How much is the longest that's safe to go?

I'm in day 31, fortunately, not loosing anymore weight, sharp, swimming and living just my regular life, feeling great.

My body doesn't give a sign of breaking up, though I heard that sometimes specific systems may collapse. So how much is the longest we can go safely? I don't recall the book stating a specific number.

Please let me know if you fasted for longer than 40 days, or if you know how long is safe.

Thanks,
