How BIG is your handbag?

As recently, big bag (or oversized bag) become more trendy, health experts warn that it can be a key serious problem.

Quoted from reuters:

Bags for women have become bigger and heavier as designers combine briefcases with handbags and straps have become longer but the extra leverage has many patients complaining of neck, shoulder and back problems.
"I see so many women with neck pains and headaches and what I usually do is look for their purse and pick it up," said Jane Sadler, a family practice physician on the medical staff at Baylor Medical Center in Garland, Texas.

"We take it over to the scale and weigh it and usually they're anywhere from 7 to 10 pounds (3.1-4.5 kgs)...We're really going to see women with more and more problems later on if we continue the big purse craze."
William Case, a physical therapist in private practice in Houston, Texas, said an aggravated neck or shoulder can lead to upper back problems, meaning pain may then be felt while working at a computer or playing sports.
He urged designers "to place a cute, educational caution tag on all bags to inform of potential neck and shoulder dangers."
Above all, he recommended correct posture while carrying bulky purses, keeping the head and shoulders aligned upright. Patients should also frequently change the size and weight of purses carried.
