Healthy Skepticism, Unhealthy Skepticism
There's healthy skepticism, and there's unhealthy skepticism.
Healthy skepticism causes us to question claims for which there is little or no evidence - questioning any or all aspects of the supernatural, for example, is healthy skepticism.
Unhealthy skepticism causes us to question claims for which there is an abundance of evidence - questioning the effectiveness and safety of vaccination, for example, is unhealthy skepticism.
On this issue, I'd just like to refer you to an open letter from Michael Shermer to Bill Maher on Skeptic Blog: Open Letter.
Get your H1N1 shots this year - particularly if you are young (under 40.) And get your children vaccinated too.
