It can be a reflection of an occasion of euphoria to describe something as "the best ever". It could be the statement of a serial sycophant, as with the late JA Samaranch, to describe each Olympics as "the best ever". I'm not in a position to say whether the 2012 London Olympic Games - held in their tightly-controlled environment of both the strictest physical and commercial security - are the best ever. But watching from my armchair, my couch, my computer desk, more often from my bed at 5 or 6 am, I'm willing to call the athletics competition at the 2012 Olympic Stadium as the most enthralling I've seen. Even in those events where the favourite(s) were so obvious.
