For years, health experts warned us to wash our hands. But, up to a quarter of us didn't, even after leaving a public restroom. Then swine flu came along, and suddenly stores can't seem to keep hand sanitizer on the shelves.

Swine flu's no good for anyone, but the healthy respect we have for it may end up being good for our well-being. A recent survey by TNS Omnibus found that out of 1015 British adults between the ages of 16 and 65, over half are making positive lifestyle changes in response to swine flu.

Sue Homeyward, of TNS Omnibus said in a press release:

Swine flu is changing the way we live our lives, and although the epidemic is having devastating social and economic impacts, we may yet see some benefit in the long term. Brits are starting to consciously consider their health and are looking after themselves better by eating healthier food, stocking up on vitamins and exercising more.

Human behavior--it's a curiosity! After all, health experts have been telling us for years that our couch potato habits put us at risk of developing unpleasant diseases, such as diabetes, cancer, and arthritis. But for some reason, that future threat doesn't seem quite as compelling as the one that's right in front of us.

There have been studies which suggest moderate exercise--not intense--can boost immunity against respiratory viruses. And fruits and vegetables are rich in antioxidants like vitamin C, which are thought to help the immune system. So, all that effort may help Brits avoid serious illness in the end. But, will they keep those good habits up when the threat has passed?

What about you? Have you changed your lifestyle because of the swine flu?
