Women's prime age

If girls were to go NS,

From the day we are born,

Pre-school
Kindergarden
Extra lessons (talent)
Primary School
Secondary School
Junior College / Polytechnic
National Service
University
Have a job
Get married
Start a family
No time for career development
Quit job to take care of family

Average age where people get married would increase if girls were to go NS.

People say that women's prime age is at 20-30 while men's at 30-40.
So girls end up having no time for themselves while boys still can have time to enjoy at your prime age?

In the end, are girls born to take up boys' jobs and sacrifice for them?

Please understand that girls and boys are different in many ways, physically and mentally.
We bleed every month and yet if we have to go NS, I really cannot imagine how troublesome it will be.
