I've actually thought of something useful I could do in time-travel that would also bring me (and a few others) joy!
I could travel back to 1987, the year Kathy Greenwood's professional show-business career kicked off, and help her become an even bigger, more famous, and more respected celebrity than she is now.
But then again, I have the feeling that a few years down the line, KGZ might just serve that purpose...but then again, by that time, big-name directors and/or producers might not want her because she's already in her mid-40's, despite looking young for her age.
