I don't understand the whole argument that women can't do physically demanding work traditionally reserved to men. I would say they can do it, maybe not all of it but a good portion. my great-grandmothers and all my female ancestors before them used to do paesant work like making hay, bundle it up on their back and trasporting it, chopping woods, cropping, watering the vineyard with a water container that weighted like 50 lbs full to carry on their shoulders etc. not as much as my male ancestors but still enough hard labor to probably exhaust a lot of modern day men. they became used to it after years of practice because they didn't have the luxury to do anything different. today we have the technological know how to apply the lever principle and implement servomechanisms and various machineries to help ease the burden of physical labor in many instances compared to the past. I believe this reluctancy to include women in heavy works comes from a more or less unconscious belief that women's life is more valuable than ours because they are child bearers and they shouldn't waste themselves doing too much physical or hazardous work. whenever someone mentions gender quotas is always about leadership positions or company boards and no mention of steel mills or constructions. :-(
