"Major" is subjective but to make things as clear as I can, anything serious for his age will count for a No. Falling on the floor and getting all bruised up or catching the flu would be major for him. I'm just trying to weed out someone trying to be like "oh they mentioned he was on meds we didn't know about before, that's an announcement about his health". If his death is announced along with another health event, that's a Yes. If he goes into a coma that eventually kills him, but the coma is announced first with some lag in between, that's a No.
