Coffee Doesn’t Actually Stress You Out
Your daily coffee might be doing more than waking you up. A new study published in Nature Communications found that regular coffee consumption may positively affect the link between digestion, mood, and cognition. Researchers also found no major change in physiological stress markers like cortisol linked to coffee consumption, suggesting coffee may not actually increase…

JFC no, formaldehyde is NOT an ingredient in vape fluid.
It is propylene glycol and vegetable glycerin with artificial flavors and nicotine. Essentially a miniaturized fog machine, with nicotine.
I’m not claiming that it’s healthy, but my god I can’t count how many times people have told me I’m vaping embalming fluid. I am a funeral director for god’s sake, I know what formaldehyde is.

Had a lung tumor, not your typical lung cancer, but a carcinoïd tumor. doctors says I might have that since I’m a child, it grows very very slowly.
My right upper lobe got completely obstructed over time without me knowing.
One day I did a control for some pain that were unrelated, they called me the same day to announce they found something weird.
5 month later, got my upper lobe removed, got some minor side effects of the surgery, but I’m able to do sport and I’m quite well recovered.

9:33 formaldehyde is not in vape juice. Nicotine isn’t a problem, other than addiction and delivery method. The unknown is the flavouring. Most seem ok so far, but no one knows long term if there is any issue. Other wise it’s just propylene glycol and vegetable glycerin. A lot of the scary stories are kids who vape illicit weed carriages that are adulterated. And this gets mis reported.

@lentoperoavanzo4007
May 2, 2026 at 8:43 pm
I was going to make this exact comment. If you put a balloon underwater and then stretch it, the pressure differential causes water to be “sucked” into the balloon. When the diaphragm flattens, it creates a *VACUUM* in your chest cavity, which causes the lungs to stretch in order to fill the vacuum, thereby creating a pressure differential that causes air to be “sucked” into the lungs. I don’t understand why this guy sees a distinction.

You say it you can “control the lung” but you’re not controlling the organ. You control your diaphragm, a muscle, to expand your chest and air simply gets in. The lungs are passive. It’s like doing a lot of abs mobility or massaging your belly with your hand to stimulate your digestion

Reminds me of my favorite disease: Ondines Curse. It is a particular kind of stroke where the involuntary respiration drive gets broken. If you fall asleep you die. So these people need nocturnal ventilators. The reason I like it is the story behind the name. Ondine was a cool Greek dude who got lucky with a nymph. He cheated on her and she did not like that. So she cursed him such that all his autonomic functions became voluntary. He had to will his heart to beat and his lungs to breathe.

I like how the presenter mentioned hemoglobin in his description of air intake into the blood.
When trying to explain complex processes, it’s a fine balance of using common and more directly accurate medical terms. Someone in the audience that doesn’t know many medical terms will now recognize Hemoglobin as it carries oxygen. Whenever someone gets lab testing, a person’s hemoglobin level in the blood is one of the most important test results.

3:45 I don’t doubt this man is a doctor, but a few things in this video have had me raising eyebrows. This one in particular so far. COPD isn’t “also known as emphysema”. COPD is the umbrella term for 2 progressive incurable lung disease caused by Emphysema OR Chronic Bronchitis which have different pathologies and presentations.
@KaedennYT
May 2, 2026 at 3:34 pm
Another thing: people report “choking on air” or spontaneously coughing without an obvious cause. This is always caused (in my personal experience) by a drop or two of saliva entering the trachea. The vigorous coughing that follows forcefully clears that saliva, and (again, in my experience) drinking some cold water (or really anything) can help relax your throat.

You don’t control your lungs. You can’t. You control a muscle like your others which give it space to let the atmosphere force air inside or squish it to force it back out. So there are no pathways in the brain to control anything that’s not a muscle

Can we be more precise with “it probably isn’t good for you in the long run?” like yeah formaldehyde is used to preserve bodes in certain quantities but what are the actually risks of it in vape juice?

@Andreas-ov2fv
May 5, 2026 at 11:58 am
I’ve had three lung collapses (primary spontaneous pneumothorax). For me, it felt like pain under the shoulder blades that was made slightly worse by breathing and standing. The fear of having “sudden chest pains” will make it seem worse than it actually is, it can actually be quite manegeable if you relax and sit down. You do need to get to a doctor promptly to get a chest x-ray, and to make sure it’s nothing else, but your life is not in acute danger unless there are other circumstances like being on an airplane, diving or in some other kind of pressurized environment. (Gas expands when there’s less pressure)
It’s not ambulance urgent, but it’s more than “I’ll sleep it off” urgent. It’s call a taxi and grab a book, toiletries and a phone charger urgent, I’d say. Don’t worry if the ER personnell doesn’t seem to take it seriously, this is quite a room temperature issue for them compared to some of the stuff they have to deal with. And don’t leave the waiting room just because they make you wait and the pain subsides, that’s just your posture and lack of activity making things easier for your other lung.

I had a spontaneous Pneumothorax back in 2021. All I was doing was swinging on a swing. It was very mild (upper portion of my right lung.) Thankfully? It settled down and re inflated on its own without any chest tubes etc. Since have found out it was due to HSD/hEDS!! To feel your lung literally shift in your chest cavity is not a pleasant experience at all!! Thankfully? Such has not re occurred ever again. (And it better bloody not!) It is NOT a fun time!! Very painful, very very scary! I am grateful my body proceeded with mending the issue without any surgical intervention!

Do psychopaths and sociopaths experience the yawn contagion?

8:20 I always thought of hiccups as a glitch in the system basically and they happen to us to regulate our breath, and kind of same with yawning except it’s a way to make your brain less tired or something

16:39 I’ve had a spontaneous pneumothorax (a collapsed lung) twice. Frist at 16 the second at 20. After that, there are times i will stop and just focus on breathing. Just to make sure I’m still breathing. Not fun with a tube in your chest at the hospital.
