Important - we don't eat cows. We eat steer. Cows have been bred over the decades and centuries to give birth and milk, not to yield meat. That's important, because some cows are heavier than their steer counterparts (Holsteins, for example).
Naturally induced miscarriage is the act of using a combination of herbs, vitamins, massage, visualization and prayer to cause the body to miscarry or abort a fetus without mechanical or surgical intervention. The body itself is induced to expel the fetus.
During pregnancy, the key factors associated with an increased risk of miscarriage were alcohol consumption, lifting weights of over 20 kilograms every day and regular night-shift working. According to the research, reducing all these risk factors to very low level could prevent around a quarter of miscarriages.
