I notice daily that many young women are have stopped dieting and exercising. I don't understand why.
are have > have
I got lost trying to think of what all the "other reasons" might be but they all come down to wanting to improve your image or self-image I guess. I've known women who weren't the least bit in danger of being thought of as overweight but who still went on a diet each spring so they'd look better at the beach the following summer which never made a lot of sense to me since such diets amounted to losing a few pounds no one but the dieter noticed, not making some major change.
So, yeah, I didn't notice I hadn't finished when I posted. I often get interrupted around here and it seems like writing a comment attracts interruptions. Sorry.
