As a long time exerciser, I have noticed that as long as I do a lot of cardio, I never get colds or the flu. As soon as I stop or take a break for a month or so, I get a scratchy throat.
I’m quite the couch potato, but I’m at least pondering the idea of exercising. ;-)
I see both sides of this. I understand the suspicion that this is just a way for government health care to say, “We won’t treat you. It’s your own fault for whatever you have. Take a hike... literally.”
On the other hand, we are getting too many tests and pills, and they all risks. In many cases, there actually is little or no benefit, but doctors and patients have bought into the idea that more is better, no matter what, when it comes to tests, treatments, etc. Many of the studies that supposedly show benefit are not what they seem. There is a lot of bad science out there, and any time you hear of the next miracle, be skeptical.
If you’re sick, see a doctor. If you’re well, educate yourself and do what you think is right for your health. Don’t mindlessly accept all the tests and pills that are being pushed on us from every side. The experts are often wrong.
