She's right. Women in their 20s are indeed very cute.
10,000 days old 27.4 perfect, looks and body good, some life experience but still flexible in life.
Women have their most options in their early 20's. They are cute, they have a young metabolism which makes it easier to stay slim. They have lots of guys wanting them.
Arrive at 30, and they have far fewer options. The best guys have mostly been taken, and many of the guys who are still single in their 30's are either single for a good reason, or are divorced, bitter and cynical.
After 40, women pretty much have to accept whatever they are offered, or stay single.
