I think there are pictures of her where she could easily pass as a woman in her late 30s/early 40s (I don't mean to be cruel at all, I'm going by the looks of my own family members for comparison and some of them apparently look way younger than they are!) and than again as someone who's not past her 30s yet. See, my Mom just turned 50 and she manages to look younger than Kate does in some of her candids. It's just strange to me. I guess sleep, free time and eating well does a lot more for a woman than one might want to admit.
