Here's the story of why she slowed down her career considerably.

She did really g00d in brady bunch!!!!!!!!

Her character on the Brady Bunch was so essential that I cant picture the series without her. Sherwood's original idea was to have a serious housekeeper and the mom be the comic. Ann was perfect for that role. The crazy part is supposedly she was not too fond of kids.
The part of her life I am most fascinated about was the Brady Variety Hour. Ann did every reunion show and even did a cameo on the Brady Bunch Movie. After the first and successful show of the Variety Hour they felt Alice was needed and she was brought in. However she supposedly hated the experience so much that she declined every interview about the subject the rest of her life. Now THAT is a negative experience.
