I know more than a few women who enjoy reminding their husbands that men have shorter lives. It can be a running joke in some marriages.

We know that statistically, it's true – but a new study finds that while women are living longer, they're not necessarily living better, especially during those later years.

The study, presented in May at the annual meeting of the American Geriatric Society's annual meeting, found that women have higher rates of obesity and arthritis, and a higher risk of disability as a result.

In fact, senior women have up to 2.5 times the disability rate of men the same age. Obesity and arthritis account for nearly half of that gender gap.

The study also found that women are more like to suffer from bronchitis, vision problems, and fractured bones.

Men were more likely to suffer from emphysema, heart disease, heart failure, stroke and diabetes, which helps explain those shorter lives. Men are also more likely to suffer from hearing problems (or at least that's what some of them tell their wives), and walking problems due to narrowed leg arteries.

Researchers believe that women tend to put on more weight after childbirth and menopause, starting them down a road towards obesity and disability later in life.

The great tragedy here is that conditions like obesity and arthritis are completely within your control, whether you're a man or a woman. Unfortunately, too many people refuse to make or even recognize the lifestyle changes they need – and pay for it later on.

Don't let that happen to you.

You can control and even reverse arthritis by following the three simple steps I outlined in the May issue of Health Revelations – and if you subscribe now, you can read all about it by going into the online archives.

It's a lot easier than you may think, and involves no drugs or painkillers. In fact, you can kiss that aspirin jar goodbye.

Not only that, but when the June issue comes out you'll discover the body's fat-making switch. I'll even show you how to turn that switch off for good, wiping away obesity, heart disease and even diabetes.

So, if you're a woman, you can live those extra years in much better shape. And if you're a man – well, then maybe you can keep up with your wife!
