Janey has forty percent less upper body strength than Johnny and she typically is only in the military courtesy of grossly reduced height/weight/physical-fitness standards. Johnny can't get pregnant and ask for 14 months off. Ultimately, because only the Army will be getting draftees, John will be the better choice to serve. Jane can volunteer if she wants; I'd prefer she not be given the lower standard tests they now hold her to.
You missed the part of my post that said put Janey in the non physical jobs that require the 40% higher strength. Or have the contracted all of those jobs out?
