Saw it on the news the other day. Martin was involed in some 5 rider pile up at I can't remember which round. Anyway when the dotors were gluing him back together they found a cancer in its early stages in his liver, and got rid of it pretty quick. That crash potentially saved Steve's life (Best thing a Petronas has ever done) Pretty lucky if you ask me.
Bostrom sounds like Mladins challenger, but like you said he's fast "when his heads right." I don't know much about the guy but it seems like hes one of those riders who need everything to be perfect to perform. And its never always perfect, you know? That's one of Rossi's skills (Along with his confidence, anticipation, determination, intelligence and perfect lines). He dosen't need everything to be perfect.
