As a Home Engineer and Coordinator, before returning to teaching, this time span was 23 years from my freshman year at Scripps. With the children grown, I was on my own. I didn't really have time to think of advantages or disadvantages. I hane had an extremely interesting and varied life for which I am thankful, although it is not the life I planned at age 19. My life has been unusual for a woman of my age.
Times are different now.
I think it is up to the individual, her abilities and capabilities to decide what is best for her.
