[Spoilers] The réal age gap difference between Darlene and Wyatt is surprisingly shocking

So in reality, Darlene is 68 years old, and Wyatt is 21, so if do the math correct, 68-21=47, that means the real difference of age gap between these two is 47 years old. I kinda feel shocking and surprised although Wyatt in the show appeared to be older like he is in his late 20s or early 30s. So again, is it reality are like this when a older woman engaged or dating a younger man in a romantic love relationship although their big age gap difference?
