'Adapt or die' is a law of nature that applies perfectly to professional sport - and particularly to F1. It's easy to fall foul of this, especially when adaptation is essentially all that colossal amount of time and money is spent on doing each year. F1 is forever evolving, so its teams are too, but what to do when evolution leaves you eating dust?
There's no sadder sight in sport than the slow, public decay of a once-great competitor valiantly trying, but failing, to recapture past glories. That deep-rooted determination never to quit is at the heart of what it means to compete professionally, but at the highest level there's nowhere to hide once your reactions have faded and legs have gone.
When you're still so invested in trying to find new ways to be better, faster and stronger, it can be difficult to see what's going on around you. Even if the self-awareness is there, accepting the circumstances is like admitting defeat.
