Some things I've done, that you might not have:
1. Had lunch made by Ursula K. Le Guin in her own kitchen. Dessert was a chunk of her Tiptree Award.
2. Worn a button at Worldcon reading "I know who won the Hugos, and you don't" - and it was true.
3. Circumnavigated an entire country, by foot. (And by that I mean, walked all the way around it outside its borders.)
4. Performed in a play using a live geyser as a prop.
5. Sat in Gerald R. Ford's office chair, in his office; and on the Woolsack, in the House of Lords. (No, Pat, no, don't sit on that!)
6. Made the sound of one hand clapping.
7. Survived riding in a car that rolled over and played dead on the freeway.
8. Visited a roadless Alaskan fishing village 50 miles from, well, anywhere.
9. Eaten a haggis. Eaten another one.
10. Stood right next to my three brothers in four different states.
Some common things I've only done once:
1. Ridden a roller coaster.
2. Danced to a rock song.
3. Gotten married.
4. Visited Scotland.
5. Worn a tuxedo.
6. Eaten sushi.
