Yep!
That is what we have just started.
I don't know but for Young, Middle and Old age by DW's definition is each is a third of your life. Thus if you are going live to 90, middle age starts at 30, old age at 60. Not an inspiring thought!
Are you my older daughter? Well, I guess not since she will be 27 in March. But your description of yourself fit her at 22 (the height hasn't changed). Because of her migraines she didn't start Community College until she was 24. People figured she was a high school student taking college courses. She started as a 2nd semester freshman at Mt. Allison January last year at 25, fit in well with the Freshmen by appearance. She was happy to find out that there were a couple of other mid to late 20 students in her dorm.
