These observational studies are pure bullshit.
Did you know that using a remote garage door opener is associated with a 20% increase in longevity? I guaranty it is. At least that. Because almost every person with a remote garage door is white, middle class or better, suburban and mostly not East Coast or any urban ghettos.
So F****** what.
Three glasses of red wine per week but not more that 6 reduces heart problems by 20%. I wonder why . . .
I remember a study that came out in the late 70’s or early 80’s that said people were better drivers after ONE drink.
