Tom Brady considers concussions to be part of playing football and doesn't worry about their long-term consequences.

"I'm not oblivious to them," Brady tells CBS Sunday Morning. "I mean, I understand the risks that, you know, come with the physical nature of our game."

Brady's wife, Gisele Bundchen, had said in a May interview that he has had unreported concussions and she worried about his long-term health.

Brady wants to continue playing until he is 45.

"I do want to go out on my terms," he said. "I do want go out playing my best."

In light of a recent study that found CTE in the brains of 110 of the 111 former NFL players that were studied, Norah O'Donnell asked Brady what he thought the effect would be on the league.

"I don't know what the future is going to look like, you know, and I'm not going to pretend to predict it," Brady says. "And I'm going to do everything I can to take care of my body in advance of the, you know, of the hits that I'm going to take on Sunday."
