Are you one of those people who always gets sick every flu season? While it's important to protect yourself with the flu vaccination, don't forget to exercise as well. It may just double your chances of staying plague-free.
Flu shots themselves are usually only about 70 per cent effective, depending on how many antibodies it helps the body produce. It's common knowledge that those in good shape are better equipped to fight the flu, but even the elderly, who don't often respond well to inoculation, were able to improve their odds with increased exercise.
There's still good news for the exercise averse: all it takes is a single 90-minute workout session after getting the shot to double your body's antibody response. But until then, trust no one. [New York Times]
