Remember Robert (Bob) Novak, the famous news reporter, TV commentator and columnist?

He only found out he had brain cancer after he struck a pedestrian in a DC crosswalk while turning. The pedestrian was only mildly injured due to the low speed Novac’s car was moving at. But what disconcerted the reporter was that he had not only not seen the pedestrian, he didn’t even realize he had even had an accident at all until stopped by a witness about a block from the accident scene.
Subsequent examination revealed he was essentially blind on his left side due to the brain tumor. He was still visually functional because of compensation over the long period of gradual decline to blindness on his left side. The blindness was not in his left eye but in the portion of the brain that processed its optical information.
He was 77 at the time of the accident.
Both Senator Ted Kennedy and Republican Party political consultant Lee Atwater only discovered they had brain cancer after experiencing seizures. They were asymptomatic prior to the event. At the time of their seizures, Kennedy was 77, Atwater was only 39.
