Eggplant is a textural thing for me. I just don't like it. Fresh spinach is a-okay, cooked spinach is not.
On the topic of living food: you can get raw octopus tentacles that are still wriggling (freshly lobbed off). I can't remember if Hulky tried it when he was stationed in Korea, but I think he said the trick is to bite it once and swallow quickly. Or maybe just swallow quickly.
