Earnhardt Talks Racing Concussions, Promotes New Book

Dale Earnhardt Jr. appeared on ABC’s “GMA" this morning to promote his new book, “Racing to the Finish."

ABC’s Michael Strahan noted Earnhardt retired from NASCAR "due to complications from more than 20 concussions. … Why do you want to talk about it now?"

Earnhardt: “Sudden symptoms were coming back after these crashes, and they were getting more and more pronounced with each crash. … I knew that I was putting myself in real danger by continuing that career long-term."

Earnhardt said of his farewell '17 season, "I had a great time doing it and was able to close the book on my career my own way, and I was completely comfortable with that decision. I still am today" Good Morning America Show on ABC, 10/17
