'Ms.' always flouted the rules of the ad world that say, especially for products directed at women, that the ad must be connected to the editorial. You don't have food ads unless you have recipes. You don't get clothing ads unless you have lavish fashion coverage. We never did that; every other women's magazine does.
Mama grizzlies mate later than other bears. They have two cubs instead of four. They wait four years - about twice as long as other bears - between having cubs. And after they're pregnant, if winter is hard or their health is not good or the food supply is uncertain, they re-absorb the embryo into their body.
