This is taken from correlations with facebook likes. There's a lot of interesting observations here. For instance, introversion correlates very strongly with "nerd culture" stuff. Openness seems to strongly correlate with left or right politics. Emotionally stable people seem to like sports and outdoor activities (adding to a weird theory that lack of sunlight and exercise causes depression.)
There is nothing weird in theory that lack of exercise causes depression. The human body needs physical activity, it does not feel as good without it. You don't have to try 10000 people for years to know that, you can do it at home in a week.
While it might not be causing depression instantly, feeling bad in your physical body certainly doesn't help depressive tendencies.
Also lack of sunlight means less Vitamin D production. It's a big problem in northern countries where people have to take Vitamin D supplements.
Some of that stuff is considerably culture dependent, so I don't know that I'd call it "The most interesting", but it is fairly thought provoking to a Western perspective.
What stood out to me was how Rap & hip-hop correlated most with Conservative and Relaxed types, I didn't expect that at all.
