I saw an interesting report on CNN the other day. Dr. Sanjay Gupta was talking about G force.

G force has always been interesting to me -- ever since Jim told me that our favorite IHRA driver, Terry McMillen, reaches between 3 and 3-1/2 G's behind the wheel of his Top Fuel drag racing car each time.

But I've never really understood how G-forces worked and how many G's did what to your body.

So here's what I've recently learned...

Do you like lists as much as I do?

I can't tell you how many times I want to know "the best" or "the top" things in a particular category.

The following site is pretty amazing because it tracks all the best lists that appeared in 2007 -- for virtually every topic under the sun...

Here's another fun online game. But this one has a purpose: To help end world hunger.

FreeRice has a custom database containing thousands of words at varying degrees of difficulty ... FreeRice automatically adjusts to your level of vocabulary. It starts by giving you words at different levels of difficulty and then, based on how you do, assigns you an approximate starting level. You then determine a more exact level for yourself as you play. When you get a word wrong, you go to an easier level. When you get three words in a row right, you go to a harder level. This one-to-three ratio is best for keeping you at the 'outer fringe' of your vocabulary, where learning can take place."

There are 50 different levels, but it's supposedly quite rare for anyone to make it past level 48.

Why does Montel Williams wear non-matching earrings that are so big?

These days, the left one is hoop-type and the right one is a stud. Neither is simple and understated. Instead, they're very flashy and much larger than your basic earrings. They're so distracting on camera... the diamonds "glow" every time the camera angle changes on the set. It's just a little much, if you ask me.

Why does Kelly Ripa always dress as if it's summer during the winter months?

I'm guessing it's to show off her well-toned arms... and legs.

Why does Regis Philbin continue to "put down" things on his own show?

He's obviously becoming less and less happy with the show's format and content these days... and he's there less and less too. Must be a sign. Next year, he's taking off Fridays and Thursdays! (It's sounding more and more like the Kelly and Regis show instead of the Regis and Kelly show every day...)

En route from Minot, North Dakota to Edmonton, Alberta Canada during our recent 2-week trip in an RV, we spotted this:

Jim and I figured it had something to do with an annual tradition with the local high school. I thought it was probably a Class Reunion activity each year.

So I researched it a little and found this...

In Canada, they definitely love their rocks.

Not only are there rocks in the hillside, and practically every direction you turn... but the people who live there have found ways to put all those rocks to good use.

They're used as signs. As memorials. And as really cool statues. In fact, you don't see much "graffiti" in Canada. Instead, you see rocks used to spell out various messages along roads and hillsides. It's quite interesting.

But my favorite is the Inukshuk!

Perhaps you've seen it...
