Warning: WTF will be used frequently. If you don't like cussing then don't think about what it means when you read it.
A couple of weeks ago I bought a home radon test kit ($12). After getting the results I dug for more information with the help of my wife (my wife is the head of reference at large Denver library- her job is to find information). Radon is known for being the second leading cause of all lung cancer cases in the US (WTF!?). I also found how this data was collected. Apparently "they" studied a group of miners. Miners are exposed to the most radon which leaks from soil. WTF? They didn't take in to account any other factors like smoking. They took the number of cases of lung cancer (~30% in the study group) then assumed an average amount of radon in a typical home and extrapolated the amount of exposure needed to match that of the miners... the assumption is that you would need to spend 18 hours per day in a home with high radon levels for 70 years to equal the exposure of the miners studied. WTF? The study group of miners was also very small.
BUT. Two very well done studies on the affects of radon showed evidence that radon has no bad side effects (unless you smoke) and that it may actually be beneficial. WTF? So we go from a leading cause of cancer to it being beneficial. WTF.
That story isn't actually what the post is about, but it's a little relevant. Today I dug once again to find post vasectomy information and was able to find multiple websites (urology.com is one. How can they be wrong?) saying that you can exercise "as soon as you feel like it". One site actually said light exercise may help to reduce swelling. Another site said 2 weeks. One said no sex for 1 week (WTF!) and another said 48 hours. One said to NEVER take ibuprofen after and another said take an NSAID no matter how good you feel. No bathing (WTF?), bathing is OK. Wear support for a week, only wear support to bed, no support. Swelling is normal, call your doctor if you have swelling. WTF? So it seems that if you don't like the answer to something, keep looking, the answer you want is out there.
