Fans are so selfish! Of course we want to be entertained by our favorite entertainers until WE die but THEY would rather retire before 70! Cohen -who is now 80- said in the past that he didn't think he would ever have to go on the road again at his age. Studio recording is OK but touring is exhausting. Now most of them need that shot of adrenaline they get on stage that's why they can't stop for long, even when they can afford it!
