If you didn't know the celebrity in the photo last Friday, I'll give you another week to think about it.
(I saw this on the internet and I have great trouble doing it.)
This week I have a game you can play in the confines of you own home. Make two fists. Hold them up in front of you with the fingers toward you. Now, in the left hand point your thumb directly up. In your right hand, point your baby finger directly up. Now, simultaniously switch to left hand baby finger up and right hand thumb up. Go slow if you have to. Now, back and forth. Make your brain work.
Now, here's one I can't do with my right hand although I could when I was young. Hold up three fingers. I can do it by placing the thumb over the index finger but I can no longer do it by placing the thumb over the baby finger. I can only do this with my left hand.
Can you raise your ring finger all the way up without the baby finger moving? I can't. Is this another sign of old age? Tell me in the comments how you did with the finger movements.
