I watched it out of curiosity, too. I think 1 or 2 of the older women were in their late 30's. Not sure, though. But, I did observe that the older women they selected seemed to appear younger than their actual age. And some of the younger women seemed to appear older than their actual age.
I didn't particularly care for how they introduced them. The older women were paraded out one at a time and introduced to him, each one telling their age to him.
And then when they brought out the younger women, they were all shown in one shot, all of them posing seductively. All such a set up.
I didn't know that this guy wants kids. I think that will play a huge role in how this goes. But, on the other hand, in the very first episode, he admitted that he had not ever dated an older woman before, and I think he was a bit surprised at his own feelings on the issue. So, who knows? Guess, I'll have to keep watching and see how it turns out.
