Sometimes Linda forgets where she puts things. I watch her search and search for something she misplaced. She sometimes calls me Chip instead of Choopie. Now I can share with her why. A study from Virginia University found that metal powers peak at 22 yrs; and start to dwindle at 27 yrs. Reason, speed of thoughts and spatial visualization and puzzle-solving all decline in our late 20's. In people years, I'm almost 21. That means that I am at the peak of my smarty-ness. It's all downhill after this. I'll probably miss the pee-pee pad; eat cat food instead of dog food and forget where I hide my toys. Oh wait, I already do all these things. Maybe the rules are different for dogs.
