DAVID: Not to compare dhw to the experimental animal! But it may help the aging brain, and I am certainly using chocolate for that reason, and that reason alone. http://phys.org/news/2012-09-chocolate-snails-smarter.html-During my many years of scientific experimentation in this field, I can state categorically that my memory has functioned at 100% capacity in relation to my daily intake of chocolate. I have never missed a mouthful. I am therefore not in the least surprised to hear that snails and no doubt other of my fellow creatures have experienced similar improvements to the memory. I should add that there are countless further benefits that have been scientifically proven, and I wish I could remember what they were.
