How old is your brain?
One of my sisters sent this little test to find out. Since the instructions are in Japanese, here's how to do it (unless you can read Japanese...)
1. Wait until the Start button shows (big letters say "start." Not too hard, although a certain sister of mine had a hard time finding it).
2. Wait for it to count down 3-2-1.
3. The screen will display numbers in random order. When the numbers disappear, you have to click in the circles in the correct lowest-to-highest sequence. It starts out easy, with 3 or 4 numbers, but adds more as the test goes on. When it's done, it will display your brain's age (supposedly). If you take the test multiple times, you get different scores. Of course, I would never do that. Absolutely. Not.
So. How old is your brain?
