After surviving 16 years in the Formula 1 viper pit, you'd expect to have acquired a few enemies. There would be a scar or three, surely, from knives inserted between the shoulder blades. You'd want to make sure you could still count all the fingers on your hands after innumerable handshakes of questionable integrity.
You'd have grown a hardened shell, unseen but impenetrable and ever-present, to guard against unwelcome interaction. And most certainly, after 284 grands prix and counting, you would expect your enthusiasm to have dimmed somewhat. Yet despite having essayed an enviably long and competitive F1 career, none of this applies to Jenson Button.
Though undoubtedly now an elder statesman in a driver cadre that includes such eager pups as 18-year-old Max Verstappen, Button remains sharp, focused, hungry... all the myriad attributes needed to make up the package of a complete grand prix driver.
