Well I live in the southern U.S. and I can Promise you there is women here in their late fifty's that look like that. I have a sister in law in her late 50's that does and she has a sister in her early 60's That I promise you looks better than Monica. I don't lie and if I ever say something that I find out isn't the truth .I look up that person and apologize.
Well, then you have two genetic wonders there that I would deem next to impossible, without spending half your life keeping your body in form AND probably cosmetic surgery.
And also, even IF those two ladies are indeed that old, then they would be the exception, not the rule.
What you are doing here is using anecdotal evidence as objective evidence.
It's like the guy telling you all so-and-such are criminals, because he has encountered several who are.
You are using your personal experiences and extrapolate them to everybody as if it has to be like that in general.
Normally women in their late fifties look nothing like that.
I've seen some great looking gilfs, but even they can only fight the passage of time up to a point.
