I am not Dr.Drew, But i am a Doctor Of Life Science, In my hub "Can't sleep,gotta go to work in the work in the A.M." i attempt to explain what kind of doctor I am. After close examination of your question my analysis tells me it should be the other way around. Is 20 for a woman the new 40yrs.old? The 20 yrs. old females appear to be more astute now at 20 like a 40yr old doing so much more, in terms of family, working, voting and creating ways to make this a better world.
