Science & Fun - Jonathan Graehl

From Seth Roberts:

A new study in JAMA found higher salt consumption strongly associated with less death from heart disease. The association with total mortality (more salt, less death) was almost significant.

Add physical exercise to the list of possible confounds for the apparent truth that even heavy drinking (of alcohol) is healthier than abstinence (other likely candidates: a social life):

“Light, moderate, and heavy drinkers worked out 5.7, 10.1 and 19.9 minutes more per week, respectively. Also, drinking resulted in a 10.1 percent increase in the probability of vigorous physical activity.”
