The Scientopia Guest Blogge now has an ophthalmologist explaining that the reason we've all heard that carrots are good for your eyesight is because the Royal Air Force deliberately lied about it during World War II.
Shocking! However, as all's fair in love and war, it was justified at the time. The alternative would have been to admit the truth about newly developed radar technology, which (rather than good eyesight due to prodigious carrot-eating) was helping RAF pilots hit enemy targets at night.
Instead, we got an elaborate fiction about carrots being good for your vision, which still echoes today.
At least now we know the truth. Thanks, cherylmurphy!
Of course, when I go to explain the truth to someone else later I'll probably have forgotten most of the details, and I'll wind up passing on an even weirder fiction, something about how carrots enhance radar detection at high altitudes, and then that will echo through the generations. This is why it's so hard to counter misinformation on the internet.

Sometimes You Want the Numbers
A good point on FWD/Forward about how touch screens can be problematic for people who can't see them well.
If you want to pay with a debit card at the grocery store, but you can't see the numbers on the touch screen, what are you supposed to do? Tell someone your PIN so they can type it in for you, and then also potentially use it to take your money? Hmm.
I mean, I suppose in the grand scheme of things the likelihood of someone memorizing your PIN and then also happening to get hold of your card is small, but still, I certainly don't go around telling people mine. And if I did have to tell someone for some reason, I'd feel compelled to change it as soon as possible.
Which should not be considered a reasonable solution for people who can't see touch screens, since having to keep changing your PIN, and remembering a new one every time you go shopping, is few peoples' idea of convenient.

Random Updates
Eyeballs sore and itchy. Hate these seasonal allergies. New glasses pretty fabulous, however.
Spouse was sick today, but apparently it's not the plague since he's still capable of walking and eating some soup and toast. The flu may have bypassed us for now.
Gotta get up unpleasantly early tomorrow to go to a baby shower. That's just not right on a weekend, you know. Baby showers should be scheduled for 8pm, so I can sleep in and still get to Connecticut in time. Just keep that in mind when you invite me to one, oh legions.
Speaking of baby showers, you may recall my extensive rant on the doggerel associated with the invitation to one. Just because I happened to think of it the other day, I would like to share a bit of dreadful verse I myself wrote in my youth.
My sister and I had decided that our deity would be a silk flower that had been pinned to one of the bedroom curtains, and I composed this moving hymn:
Oh flower on the curtain,
Hear my prayer to thee.
Oh flower on the curtain,
Listen please to me.
Oh hear my faithful prayer,
That I am praying now--
Oh flower if you care,
Oh hear my earnest prayer,
And how! And how!
Oh yeah, that's magic. I mean doggerel. Many 17-year-olds write florid love poetry, you know.
I think in some way that excuses this.

Not Just One Saint
Well, here it is November. All Saints Day! That's got to be way cooler than Some Saint's Day. Time to party!
I party in celebration of the return of Drugs and Poisons, a nifty little blog about, well, drugs and poisons, which is presently discussing mouthwash. I don't generally use mouthwash myself, but I like those bits Wired does on "What's Inside" various things, and I'm likewise pleased to know that mouthwash is not poison.
If anyone in the world reads blogs but does not have an RSS reader, I would highlight this as a fine example of something they do that's good: a blog can lie quiet for months, but as soon as something new is posted, I've got it!
Now if I had been just going to look at the site every so often like an RSS-less mariner drifting on the internet seas, I would have been disappointed many times by now, and perhaps even given up.
This particular blog, which is rendered in white text on black, also makes me grateful for the ability of feed readers to make everything come out in a uniformly readable way. White on black looks cool and all, but I swear it makes me a little cross-eyed after I read it for a while.
Speaking of eyes, I also party in celebration of the fact that I finally got around to buying some new glasses. It's only been since July that I had my eyes checked to get a new prescription. And since April before then that I barely passed the vision test at the Registry of Motor Vehicles and narrowly avoided having to come back and wait in line for three hours again to get my license renewed.
I think no one would imply that I don't get stuff done. Sometimes. Eventually.
I also party in celebration of the end of Daylight Saving Time, which promises a little more light in the morning. Getting up in the dark is just no fun.
On the other hand, this also promises that soon it will be deep night by the time I get out of work, but these are the trade-offs we must make.

Favored by Timing
How great is this?
Not one week ago, I found that I could barely read the top line on the RMV vision test, and now just today I find that my employer has made available a new vision care benefit! I can get 40% off new glasses!
I am beloved of fate.
