Wow, this was a surprise. I know he's getting older, and they have a "new" Spock, but Nimoy will ALWAYS be Spock, no matter what. Of course, he has done many other things besides "Star Trek". Maybe he just wants to relax and enjoy life. And, even if he retires from acting, he can still write books and do many other things. Maybe even make an occassional guest appearance somewhere. I hope so.
