Thread: Shaving is good for your health - literally

Well, the title of the article is just marketing. The authors acknowledge that the relation between shaving frequency and heart disease is correlation, not causation, and then look into causal relations with other correlating factors.

Then if you read the article in full you find out that after they take into account many of the other correlating factors (once you're past the garbage dealing with their first poor attempt to do so), the residual unaccounted correlation is 'small' (I didn't find the number in the paper, so I use their qualitative description). And they acknowledge that at this point any of their hypotheses for the unaccounted part are speculative and impossible to prove.

BTW the link in the first post is NOT the actual article, it is a response to it. Here is the original article in question. In my opinion it is a rather poorly written paper with improper emphasis on a part of their research that was rendered obsolete by their subsequent analysis.
