Dentists and ads constantly push electric toothbrushes as a big upgrade that removes way more plaque and prevents cavities better than manual brushing. I have been using one for the past year and my teeth do feel cleaner but I am not sure if it is worth the extra cost long term. Friends who stick with regular brushes seem to have just as good dental checkups. Is the difference actually significant or is this complete bullshit?

I keep seeing influencers and wellness accounts on TikTok claiming that taping your mouth shut while you sleep forces nasal breathing and somehow leads to better sleep, sharper jawlines, less snoring, lower anxiety, and even reduced cavities.

It sounds wild to me. People are literally sticking medical tape over their lips overnight and saying it changed their life. Some claim it boosts oxygen levels, while others insist it can help with sleep apnea (which honestly sounds risky if you can't breathe through your nose properly).

Is there any real science backing this up, or is it just another viral wellness trend riding on cherry picked anecdotes and influencer testimonials? Has anyone actually tried it long term and seen measurable results?

My mom and teachers warned me for years that cracking my knuckles would lead to arthritis when I got older. I have been doing it since childhood out of habit and now as an adult I still do it daily without thinking. I have not developed any joint problems yet but the warning always stuck with me. Is this a real risk backed by science or is the whole arthritis claim complete bullshit?

I use external NVME drives to hold some documents, recently heard that this data can basically disappear if you don’t plug them in regularly?

One of my uncles got baited into buying some pills from TikTok. They're some oil of oregano pills for weight loss and parasites. I try to ask him "What parasites?" and he just shrugs.

Ugh. Internet illiteracy.

He says it's been making him go to the loo a lot. Are these pills dangerous, or just a placebo?

I tried searching on Reddit but I mostly find posts from Crunchy people.

I wonder if that's true

i started aiming for 10k steps every day for the past six weeks because all the health people say its the magic number for staying fit and living longer. my retail job keeps me moving but i added extra walks to hit the goal. at first it felt good but now my knees are bothering me more and im exhausted by evening without seeing much change in how i look or feel.

its free but the pressure to hit it every single day is getting old. is the 10k steps thing actually backed up or just a random number everyone repeats?

i started doing a shot of apple cider vinegar mixed with water every morning for the last month because a bunch of fitness accounts say it helps burn fat and fixes gut issues. im on my feet a lot at my job and wanted something easy that might help with bloating after meals. it tastes awful but i powered through thinking id see some results on the scale.

instead my stomach has been more upset on some days and i havent lost any weight. its cheap but the whole thing feels pointless now. is apple cider vinegar actually useful or just another overhyped trend?

I keep seeing doctors and influencers recommend high dose vitamin D supplements to boost immunity and stop frequent colds and flu. A friend of mine swears by it and says he has not been sick in over a year since he started. I have been taking it daily through the winter months but still caught two colds. Is there strong evidence that vitamin D supplements really keep you healthier or is this claim complete bullshit?

I understand the concept of being grounded as a mental state, and I know that practices like forest bathing have real benefits. I guess the best way to describe the feeling one has after a walk in the woods is "feeling grounded." My question isn't about any of that.

I'm wondering about the YouTube ads I keep seeing for "grounding sheets" and "grounding pads," where a low-level current (or something?) is run through the sheets you sleep in or a pad you stand on, and it supposedly has a whole bunch of health benefits.

Sounds like bullshit to me. Am I wrong?

I have heard this rumor for years that eating a banana right before bed helps you fall asleep faster and sleep better because of the potassium and magnesium content. My grandmother used to recommend it all the time and I still see it shared as solid advice online. I tried it for two weeks straight but did not notice any improvement in my sleep quality. Is there actual truth to this rumor or is it complete bullshit?

i started dry brushing my whole body before showers for the last three weeks because everyone on tiktok says it helps with circulation, reduces cellulite and makes your skin smoother. its supposed to be this big lymphatic drainage thing and its basically free so i gave it a real shot. my skin feels a little exfoliated but i havent noticed any real difference in puffiness or energy like they promise.

now my arms and legs are just kinda red and irritated some days. its quick to do but im wondering if its worth the hassle. is dry brushing actually legit or just another beauty trend that doesnt do much?

The cold plunge trend has exploded lately with athletes and influencers saying daily ice baths reduce inflammation speed up muscle recovery and even improve mental health. I tried it for three weeks in the mornings and it felt refreshing but I did not notice any major benefits in how I felt or recovered from workouts. Is daily cold plunging truly as beneficial as everyone claims or is this whole trend complete bullshit?

I switched back to physical books for a few months because everyone said it improves focus and sleep. I enjoyed the feel but I read slower and carried heavier bags. My sleep and focus felt the same as when I used my e-reader. The convenience of e-books is hard to beat. Has anyone compared both long term and seen a clear difference in comprehension or sleep quality?

i started drinking fresh celery juice every morning for like three weeks because everyone online says it clears your skin and reduces bloating. my friend swears by it and showed me her results. i hate the taste but forced myself to do it anyway.

my skin hasnt really improved and i feel more bloated some days. its a pain to make fresh every morning too. is celery juice actually doing anything or is it just another trend that doesnt work?

my buddy got me this "premium protection plan" for phone cases where they send a new one every couple months for like 15 bucks. he says its way cheaper than buying them when they crack and theyre supposed to be military grade or whatever. but i keep getting these cases that feel kinda thin and now im wondering if its just overpriced junk theyre dumping.

he already paid for the first 6 months as a gift so id feel bad canceling right away but i dont wanna keep wasting money on stuff that breaks easy. is this one of those things that sounds good but isnt worth it?

Had a family member claim they didn’t like organic milk because it tastes different. I have never have noticed a difference and neither had anyone in the family who was present for the conversation. So, is it bullshit and they’re trying to oddly humble brag? Or is there something that would make organic milk taste differently than regular milk?
