What utter bullshit. Next iteration of “what doesn’t kill you makes you stronger.” I notice they’re not handing out you’re-so-successful-and-tough cookies to people with chronic pain or a thing for floggers.
Also if it actually worked like the article suggests, being uncomfortable would help me ignore chronic pain, not intensify it. Or I should be able to push through a marathon no problem because I’m so great at dealing with pain. Not true.
