First off, I should share the news that a T-shirt design that I suggested a while back is now available at the mental_floss store. Get yours today, and tell 'em that Sandy sent you.

You can solve today's Brain Game by just looking at it. Having said that, the answer might be a bit esoteric - but I have to keep you smart readers on your toes!

Here are 12 terms that I pulled from a computer book. As they're shown, each of these 12 terms has something very specific in common (other than being computer-related terms, of course). You may notice that every vowel except "i" is used in the list - but that's not the answer we're looking for. Can you figure it out? Good luck!

screen saver - common - errors
access - camera - erase
secure - macro - amazon.com
consumer - recover - mouse-over

Here is the SOLUTION.

THE SOLUTION:

None of these terms contain any letters that have ascenders or descenders - parts that rise above or below the baseline of the text.

When written in lower case, half the letters of the alphabet either rise above the baseline (b, d, f, h, i, k, l, t), sink below it (g, p, q, y), or both ( j).

The other 13 letters (a, c, e, m, n, o, r, s, u, v, w, x, z) do not. And each 12 of the terms in the list are comprised of ONLY these letters.
