Do you know the number for ? http://cliphunter.in.net/ clip hunter  A: The two groups of people who would work less are youngparents and old people. I talk about a working arc where youdon't reach full-time work until your kids are in middle schoolor out of high school even. You can both be with your kids whilethey're growing up and work part-time. Then you would hitfull-time work in late 40s, early 50s, and then work full-timeuntil you're 75 or 80 and start to taper off to part-time work.
