Depends totally on her fitness level.
When Mrs Didge was in her 40s her resting pulse rate was 38 bpm. Of course, she won a state championship in triathlon at that time, so she was actually you're average woman.
It was a bit comical when she had surgery. She said the nurse taking her pulse said, "She's dead. No she's not. Yes she is. No..." It was a very slow pulse rate.
