Cool Things Evolution Left Out, #24

24. An eye on the end of your index finger. Think of it!

• If you needed to find that last tic-tac in the bottom of your coat pocket, you could just stick your hand in there and look for it... no more eating lint accidently!
• Let's say you needed to look on top of that really high shelf in the closet. No longer do you need to get a step stool or chair: simply stretch out your hand and run your index finger (with eye, remember) along the length of the shelf until you find what you're looking for.
• I'm sure there are other, less interesting uses for such a sighted digit.
