If you like sushi, you shouldn't watch either.I've been watching a show on Netflix about parasites. I really hope there isn't an upcoming episode about infection via aquarium. A lot of stuff about roundworms...which there are pictures of in the link (different kind of course). But still...ick.
I use the neti too. Boil your water, easiest in the microwave.I adore sushi. I turn off my brain when I watch those (and try to eat the best anyways). I will continue to scratch random imagined itchies while I watch the rest of the episodes, however. Last night I watched the brain amoeba. Which you can get from a neti pot (if used incorrectly), which I use, but they haven't had that episode yet either (about neti anyways).
