This guy is a crackpot who doesn't have a clue what he's talking about. Serious? I don't know the person - and the article was so and so - but the credentials of the author are stated as: 'Ray Tallis trained as a doctor, ultimately becoming professor of geriatric medicine at the University of Manchester, UK, where he oversaw a major neuroscience project. He is a Fellow of the Academy of Medical Sciences and a writer on areas ranging from consciousness to medical ethics' This doesn't strike me as a crackpot!
