    How Plastic We've Become

    In the 1967 film classic The Graduate, a businessman corners Benjamin Braddock at a cocktail party and gives him a bit of career advice. "Just one word…plastics."

    At least until menopause, women face a lower risk than men do of artery-clogging heart disease. Michigan scientists now turn up one potential reason: before menopause, one of the avenues for clearing meal-derived fats from the blood operates better in women than in men of the same age. This makes the fat less available to the plaque-forming cells in women's arterial walls.
