Advice from the old lady:
Being now in my fifties I have a long range view about this. You see being hot in youth is easy. You don't have to watch so much how you eat, you don't think about how smoking ages you; how sun exposure at the beach or in the pool ages you, how stress ages you. You can neglect working out and getting enough sleep. In youth you can be ignorant about all that.
As you get older though, your lifestyle choices come home to roost. Look at photos of Bridget Bardot in 1965 versus 1985. Look at Twiggy. Scary.
Men often loose their hair & get a poochy belly.
It takes something different to keep up your looks as you age. It takes discipline. To exercise, to sleep enough, to avoid the sun, to not smoke, to not over drink, to eat properly. The earlier that discipline develops, the better the long term outcomes.
Many women, myself included, choose men among other things for longevity in relationship. What does that mean? It means is this guy someone who has the attributes that I could see as a long term rellationship partner.
Here is what that thought process looks like (this is mine - but this will vary based on individual women's preferences, which are complex and multifactorial)
1. Is he attractive and sexy where I have desire for him?
2. Is he very intelligent?
3. Does he keep himself in shape?
4. Does he have his life together/is he accomplished & self sufficient?
5. Is he very attracted toward me?
6. Is he funny?
7. Is he masculine? Does he want to lead the relationship?
8. Does he have close relationships with family & friends?
9. Is he aloof/independent/can he be an ******* if needed, but alsobe thoughtful & kind?
10. Does he have a edgyness in his demeanor & style?
11. Does he have a big heart?
12. Is he loyal/honest/trustworthy?
See how specific that is?
Many women want men who desire kids/families.
The more objectively attractive a woman is the more realistic she can find a man who ticks most or all of her boxes.
