These are two books I recently read which I think are fascinating.
The Mature Mind challenges many of the ideas we have about how much worse our brains get as we grow older. Cutting-edge neuroscience and psychology presents a more exciting picture. After reading the book, I wish I could get involved in some work like what Dr Cohen did.
And this other author also sounds like he has been doing some fun and insightful researches. The accompanying website is great fun too. So, which way do you draw your Q?
