Scientific studies are ruining everything. First they tell us skinny jeans are bad for us, and now the man purse is on the chopping block. According to a new study (via the NY Post) a weighty man bag may be a quick way to land yourself some back pain and bad posture... or your neighbors calling you "a real fancy boy."

The British Chiropractic Association said man bags, on average, weigh up to 13.67 pounds (or 12+ bags of sugar—and that's lighter than the average woman's purse) and "should be used with caution." This includes any bag from an over-the-shoulder laptop case to messenger bag to satchel—we're guessing even Jerry's European carry-all isn't safe. Men, here are some pain-free purse-carrying pointers from Woman's Day.
