Meat that's been frozen. Yuck. I don't eat a lot of meat, but I can tell if it has been frozen and thawed. Beef (ground beef, especially) and chicken are the absolute worst. Fish is okay to freeze. I have lots of frozen fish. While I prefer it fresh, it's okay after being frozen. Living in land-locked Beefville, not much choice in the fish dept.
Pools have to be the right temperature for me to even consider going in them. I really hate the cold and in most cases would rather sweat than go into a pool that's too cold. Oddly, while I enjoy showers (hot showers), I generally detest being wet. I can't stand being in wet clothing and even a bathing suit just never feels right.
