Lol, Stefano Domenicali summed the whole thing up perfectly:
For sure we were very worried, no doubt, it was a long race to finish, maybe lost a lot of years and a lot of hair but that's part of the game. Extremely happy. In that condition you never know. It may stop any lap, it's too difficult, it's critical.
To make up for the aging and hair loss, let's do well with the new engine at Silverstone (provided we do switch it)!
