Thats why they give you the extra things on the side for the sushi, to prevent the worms from growing in your body. They dont eat at your brains, thats just stupid.
Sushi is actually very good. If you have never tried it, you really should.
Hahaha
I second that, my favourite one so far is prawn and avocado.
Although it's not sushi I really love onigiri(big ball of rice shaped like triangles with fish inside and sesame seeds on top) sort of like sushi but without seaweed.
I think people just don't like the idea of eating seaweed, if for example I offered someone who's never tasted it some sushi without telling him that iut contains seaweed then he/she would probably try it.
You should never eat sushi at shabby looking places though, could be unsafe.
