20yo women > any other age

1. Women have an extremely short prime fertility window, usually starting when they finish puberty(physical maturity) and ending when they turn 30

2. After 30, the egg count and QUALITY of those eggs drop significantly, increasing the chances of having retard children

3. Freezing eggs is not a good solution. It's expensive, harmful, and very few of those eggs will end up being viable in pregnancy

4. Even with viable eggs, giving birth in an old womb is a toss up
