It's not just about crime - it could have a lasting impact

For those who prefer to travel light and keep everything in their pockets, there's some bad news.

If your wallet is jam-packed with old receipts, coupons - maybe even a bit of money - it might be time to invest in either a man-bag, a handbag or a sturdy rucksack.

The reason being, keeping your wallet in your back pocket is putting you at risk .

But this time, it's not about being an easy target for pick-pockets (although do be wary of them too).

Speaking to the Huffington Post , New York City-based chiropractor Dr Arnie Angrist warns keeping a "fat wallet" in your back pocket is doing your back, hips, neck, pelvis and even your bottom potentially a lot of harm.

How?

The doctor explains how sitting on a wallet "creates an asymmetry or imbalance that distorts your pelvis and hips."

It's not just about crime - your wallet can be doing your neck, back and bottom some harm

Having one hip sat higher than the other causes the back and neck to compensate for the unevenness, which, in turn can lead to problems in these areas.

But that's not all.

A professor of clinical sciences at University of Bridgeport College of Chiropractic, Dr Chris Good also spoke to the news site and bore more bad news.

A full wallet may mean you're flush, but there are some downsides

He explained how sitting on a wallet can cause the spine to become tilted, or for the body to compensate for the tilt.

Over time, this could lead to serious problems for spinal joints, muscles and discs, resulting in serious pain and even failure.

As for our posteriors, according to Dr Good, a wallet in a back pocket "could cause irritation to a number of important structures in the buttocks" including damage to nerves, muscles, arteries and veins.
