I think its way easier to get girls when older than younger, if you have your shit together.
Many women in their 30s are desperate to get married, or they are relegated to a life of single/hookups. It's a win for single guys!
When you're 18, everyone has about the same income, most everyone is lean... it's really hard to stand out. By the time you're 35, most of the people you went to high school with are fat, arrested, drama, problems, etc.
in other words, most people don't get BETTER in their looks and situation with time.
