There are few moments in life when you know, there and then, that you will remember them for ever. Getting married is an obvious one. The birth of a child. Standing in the middle of a mosh pit, seeing your favourite band.
Then there is sport, which hovers agonisingly between memorable and better to be forgotten. The legacy of a kick, a catch, a last-breath tie-break writes itself as it transpires. And so it may only be later, dazed and slightly numb, that you realise the gravity of what you were witnessing.
