I have thought this several times. Here's what I think:I think that Christie seems more like mid-30's.
Jill fluctuated. She went from 35-41 by the time she graduated. Now, that is real GROWTH!
Lisa1 looked 40 to me, back acted a lot younger,
Lisa2 looks about 50, so that jibes.
Kim, to me,looks older than 37.
Jody looks about 40-45
Kelly looks like she has been through it....
