What I like about this thread is that there's loads of things that I've already "ticked" and it's nice to be reminded (most of the places on Kriegspiel's list, for example.) There are things which I can do easily, whenever I like, but which are sufficiently hard for some people that they'd write it on a bucket list (run a 7 minute mile, or visit a castle, for example.) There are things on people's bucket lists that are parts of my daily life that I should never take for granted (having children, for example). There are things on some people's lists that are completely out of reach for me (quite a lot of the non-travel bits of Kriegspiel's list, for example).
Best of all, though, there are some great ideas for things to do in the future.
