There's a difference between not eating food for a day, and not drinking any liquids for 10 days... one of these can and will kill you. Do you know which? It seems you do not.
You don't know what you're talking about though, I'm in the community and I assure you there are MANY of use that do it, some more often then others. I know a guy how once did 3 back-to-back 15 day dry fasts with 3 day breaks in between.
