Do we really think that Michael can ever catch Nico again? Not really! The younger top guys from from Alonso down to Kubica and Rosberg are probably faster by now. Michael will enjoy the challenge of competing with them as an elder statesman and driving pundit. It's much more fun and more rewarding than breaking your bones or neck on motor bikes each year or making wise cracks on RTL 20 times a year.
He will help his team by bringing sponsors in with his past glory. He is still good enough to run the second seat at Mercedes. So basically all parties can be happy to have him. Corinna most certainly is happier to have him in F1 cars than on motor bikes. The Schumi fans like me need no convincing that Michael's F1 career is the best thing to happen to Germany since beer was invented. Nothing that can ever happen to him will destroy the pleasure he gave us over the years. I don't mind one bit that he could not win an eights championship after 2004. He served his country well for 15 years and broke all records.
Card blanche from me to Schumi to have fun as an F1 pensioneer!
