Regardless of multiple brain surgeries, I have excellent balance. I don't think I am ready to cross Niagra Falls on a tightrope, however, I can ride 'wheelies' on motorcycles so well and in many different positions. I was asked by car stunt show guy 'Buzz Bundy' to join his stunt show as a trick motorcycle rider. ( I didn't)
Isn't balance controlled in the inner ear bh? Why would brain surgery have anything to do with it? Anyway glad you're here. Brain surgery sounds very scary and you've had multiple ones? Wow! Thank you for your reply and Happy Monday! :)
Back in the 50's, brain surgery usually meant some sort of physical disabilities would result. If the brain is unable to function, the inner ear might not be able to respond.
