Learn something new every day

Photic sneeze reflex -- I hadn't realized everyone didn't sneeze in response to bright light. (yes, that would make me someone who does)

And while thinking about random genetic traits, I went looking for something about tongue-rolling. I can triple-roll my tongue, as can my dad (if you scroll about 3/4 of the way down this page, you'll see an example). musicalchaos and jajy1979, can you? I was very interested to learn that simple tongue-rolling's method of inheritance is nowhere near as clear as tended to be taught in high school science when I was young, although the one page I found discussing triple-rolling says it might be a separate trait with clearer heredity. Interesting on both counts.

I'm incredibly exhausted today. I got home about 10:30pm, and didn't manage to get to sleep until about midnight (no matter how tired I am, it seems to take me about an hour to wind down after getting home before I can go to sleep). Also, it's raining, and that seems to be combining with the fatigue to make my fibro grumpy.
