I wondered about that also agt. I think that is why some males engage in a lot of physical activity , to get the blood circulating. A hundred years ago doctors would do blood letting, to try to relieve diseases from toxic blood. Some kids with problems are also cutters these days, cutting themselves, probably unconsciously trying to get rid of toxic blood. I was told by a holistic healer, that males who listen to head banging heavy metal music etc are trying to release toxins from thier blood. Males might get help dissolving blood clots from excess testosterone, not sure. Estrogen makes females more calm. Not sure what effect different gender biochemistry has on toxic blood.
If I were a male I would be very careful about what I ate and my lifestyle.
I have seen just as many sick males as sick females. Toxic blood knows no sex or gender. Diet of meat cow eggs and flour plus bad lifestyle, are equal opportunity health destroyers and killers.
