I'm 40 and I'm a low slinger. It was never really about being cool, more just wanting to be like my idols 25yrs ago; if that is cool, fine and if not, each to their own. I raised it for a while in my late 20s / early 30s but I guess I'm so set in my ways I tend to have it below the belt.
And thankfully I have a pretty flat stomach so no issues there for me
