i imagine if you ask the majority of medical practioners whether or not eating shrimp can cloud your cerebral processes, they will answer no. we dont even know for sure in what sense meat-fish is a sakana, physically, spiritually or both.”
Maybe so,but we don’t eat shrimp for the reason that the Torah tells us we cannot eat seafood that does not have fins and scales. It makes no difference if shrimp clouds our cerebral processes or turns us into MENSA geniuses. It’s assur to eat it. Period.
I also would not drink liquids that were uncovered overnight, even if the Gedolim tell us it is perfectly OK halachically because there are no longer snakes and scorpions in most neighborhoods, because G-d knows what shmutz cold have fallen in or worse, cockroaches and other wild life might still have crawled over the open container. Yuck.
