This isn't really constructive regardless of whether you're right or not. It's completely valid to e.g. both agree that exercise is good as well as criticize a specific study on the matter.
HN suffers from a peculiar obsession with theory and optimization. There's no secret to aerobic exercise: go get your heart rate mildly elevated for a while. Do whatever activity you can stand making part of your regular life, and stick with it. Do it long enough and you'll lose weight to boot. This is a simple truth. Things get complicated at the fringes, or if you want to actually train vs just get fit, but most of HN is not a fringe case unable to benefit from basic exercise. They just pretend to be to ignore that simple truth.
I'm pretty sure that HN skews far fatter than average, which is insane to think about since the average tech bro is far LESS fat than the average person.
I imagine the average HN user to look like Richard Stallman.
Why do you think HN skews fatter than average?
They must have taken a random sample.
This doesn't jive with my internal stereotype - but maybe that's because I live in the PNW. "Everybody" here boulders and hikes on the weekends.
I would love to know the waist size of the average HN user.
My money is on bimodal distribution.
Anyone telling me something I don't want to hear is clearly wrong, and probably a malicious asshole to boot. /s
