My wife is from a motorcycle racing family and we are big fans of MotoGP.
While Marc Marques is not our favourite rider, his ability to get a bike back upright is unparalleled. To my knowledge the farthest over he has been verified to come back from is 69 degrees. (63 degrees is typically the extreme limit while still in control). The key to his abilities includes never believing it is lost until he parts ways with the bike. (Plus the fact that he has the reflexes of a cat.)
When first diagnosed I told her it was like Marc when the bike is cranked over and both the wheels are sliding deep in a corner. Keep steering, apply a little power and push with whatever you have to get back on two wheels.
She has a an enormous scar from a six hour operation. The cancer has now become resistant to the most used chemo treatment but the one after that appears to be working for now. While there is life there is hope.
