I’d say she walks funny due to the fact she gets no exercise. I have PT 2/3 times a week and it’s helped my 60-year-old ass immensely. 40 minutes upper-body, 20 minutes treadmill each session. And, I feel much better!
If she had a physical disability, I'd cut her some slack even though i don't like her. I think she would look at exercise as being beneath her.
I agree; exercise becomes increasingly important as one gets older.....
