The original poster in the screenshot is “confessions of a diabetic,” and based on her avatar I’m taking an educated guess that her illness is not lifestyle-caused. That’s what makes your comment tone-deaf: a person with an incurable disease makes a statement, that other people with incurable diseases resonated with, and you start going off about lifestyle changes like it’s contributing to the conversation and not just making chronically ill people feel bad. Why bad? Because it’s a) a reminder of all the times they tried in vain to fix their condition with lifestyle changes, b) overlooks that most chronically ill people do actively engage in (often extreme) lifestyle adjustments to help manage symptoms, and c) reinforces the idea that if chronically ill people just tried harder they could be cured).

Putting “a lot” in front of your statement doesn’t negate that it’s out of context, and thus insensitive and not contributing to the discussion. It’s a case of “you’re not a member of the group of people that are commiserating here, so maybe this conversation isn’t for you to participate in.”

“Just chewing on plastic, what’s going on with you?”

Yes, most chewing gum is literally made of plastic, because of course it is.

You sound like RFK Jr. Yes most people in our modern world don’t get enough exercise, but it’s not a panacea. Exercise, sunlight, and clean eating alone won’t do more than nudge most chronic illnesses. Hell, the latest on ME/CFS is that exercise can actually worsen symptoms.

“All I needed was exercise and/or a healthier diet and I felt great!” folks were not truly ill to begin with, just slacking. There’s a huge difference, and insinuating otherwise is a giant slap in the face to those who’ve tried these things (and likely so much more) and are still struggling with debilitating health issues. To use a car analogy, regular oil changes and premium fuel won’t compensate for a broken axel.

Those devices absolutely need regular cleaning, because they will get moldy and will spew dirty air everywhere.
