Psychology :: What do we see when we look at ads?
How do consumers look at advertisements? Most marketing textbooks advance the theory that looking at ads is a predominantly ?dumb process,? driven by visual stimuli such as the size of the ad or the color of the text.

High Blood Pressure :: Estrogen deficiency can lead to obesity-induced high blood pressure after menopause
At menopause, women lose hormone protection against heart (cardiovascular) and kidney (renal) diseases, and are likely to become obese. A research team has tested the idea that estrogen deficiency in aged females may trigger the development of high blood pressure and obesity. The results of their study, using an animal model, suggest that estrogen depletion can have these effects.
