Judge every woman separately and for the love of all things beautiful, 30 is not 'old.' Lol
Certainly not in my neck of the woods, the majority here are amazingly fit, hot and beautiful well into 40s, even 50s! With youthful attitudes and spirits as well.
As I said, many look younger than the 20 year olds who live at the beach and bake in the sun all day.
I'm actually shocked when I see some of those girls, they look like old ladies with all the sun damage, not to mention piss poor entitled attitudes.
For the life of me, I don't understand the appeal, but anyway again judge every woman separately, age is just a number and get rid of your age bias and false assumptions about what a woman's age means.
That says more about you (and not in a good way) than it says about her.
