To expand on this, she was 42 at the beginning of the series and 48 when it ended. Definitely playing a role of a younger woman than you would normally expect back in those days.
Somewhat interesting too. The husband, played by Hugh Beaumont was 47 at the start of the series.
And I just thought that adults looked really old in those days when I grew up watching the reruns starting in the late 70's.
