Peanut butter and jelly...

Thanks to the generosity of some American acquaintances, I sampled my first ever peanut butter and jelly sandwich today. That and the '10 things' meme got me wondering what things I haven't done that most of my readership have.
I've not been able to list 10... but here goes...

I've not...
... smoked tobacco (I've taken snuff, though...)
... attended a non-Catholic church service
... worn brown shoes since reaching the age of reason
... been admitted to hospital for an overnight stay
... been in the United States
... eaten in a vegetarian restaurant
... read a full JRR Tolkein book
... watched a full Star Wars film
