If I'd gone away and taken a year or two to recover, my career would have been over. Mind you, for years afterwards bits and pieces of grass or rubber would work their way out of my feet. You can bounce back physically but psychologically it can be a different matter. But as far as I was concerned there was just no point worrying that it might happen again. You just try your best and hope it all works out.
Recovery is an interesting exercise.
Doctors are pessimistic. If I'd listened to them, I'd have been in bed for a year. If you work hard enough at something, you can overcome all sorts of problems. The dynamics of the accident at Interlagos were also interesting. I was okay.
