While I don't necessarily disagree with this, I'm to selfish to say that I wish he would retire. It just wouldn't be the same without him. I remember when Earnhardt Sr. died it took a couple of years for me to get back into Nascar. I'm not saying I wouldn't watch because I watched every race this year even though he missed half the season. It just wouldn't be as exciting to me because I'm a die hard Earnhardt fan.Personally, I think he should retire from driving while he is healthy. The concussion problem that pulled him out of the car this year is something that never completely heals. One hard hit and it could start again, with even worse symptoms. And take even longer to heal or the symptoms could stay forever. It would stink to see him looking like some punch drunk boxer for the rest of his life.
