A few things...

Today, I realized that I am clueless when it comes to eyeliner - so I just don't wear it.

What other things can I not do?

1. Math.
2. Look at fish and not gag.
3. See a mistake in grammar or spelling and ignore it.
4. Whistle.
5. Blow a bubble (with gum).
6. Sing (in tune).
7. Make out the lyrics to "Thnks fr th mmrs."
8. Bear to eat anything smothered in butter (I'm shuddering just thinking about it).
9. Roll my tongue (though I can bend my fingers backwards and spread out my toes, so that may make up for it).
10. Stop talking.

And that's just a short list, not including my limitations due to CFS or FMS. (That list would include decibel levels for music, hours spent awake, and certain brightnesses - as well as a great many daily activities).
