Around '97 or '98, I saw Ken Howard in a convenience store in Hollywood, surrounded by fans who were asking him standard fan questions about The White Shadow. I could tell that he was uncomfortable with the whole scene. He was giving terse, short answers, and had a grimaced look on his face the whole time. Finally, when someone asked him about what ever happened to co-star Joan Pringle, he apparently had enough and walked out of there with people still trying to talk to him. To be fair, Howard looked like he was already in a bad mood, and he did his best not to explode or snap at anyone.
As bad as this looked, I'm willing to cut the guy some slack. I later learned that about this period of time, Ken Howard was in dire need of a new kidney, and luckily, a match was found and he got the badly-needed life saving kidney transplant. He married the woman who donated the kidney to him.
I wish him health and happiness.
