I think that age as a number is not nearly as important as health. You can be in poor health and be pretty miserable at 40 or 50. If you're in good health you can enjoy things into your 80s.
If you get half a million at a certain stage you probably will get 4 million people if they are able to hear it. The touring thing is unbelievable. It really is amazing from what we did the last tour even to what we are doing now.
