| How do lungs heal after quitting smoking, especially with regards to timelines and partial-quit? Posted: 02 Sep 2021 09:56 AM PDT Hi all, just trying to get a sense of something here. If I'm a smoker and I quit, the Internet tells me it takes 1 month for my lungs to start healing if I totally quit. I assume the lungs are healing bit by bit every day after quitting and it takes a month to rebuild lung health enough to categorize the lung as in-recovery. My question is, is my understanding correct? If that understanding is correct, if I reduce smoking to once a week will the cumulative effects of lung regeneration overcome smoke inhalation? To further explain my thought, let's assume I'm starting with 0% lung health. If I don't smoke, the next day maybe my lung health is at 1%. After a week, I'm at 7%. If I smoke on the last day, let's say I take an impact of 5%. Next day I'm starting at 2%, then by the end of the week I'm at 9%. Of course these numbers are made up nonsense, just trying to get a more concrete understanding (preferably gamified :)) . I'm actually not a smoker, but I'm just curious to how this whole process works. I assume it's akin to getting a wound, but maybe organ health works differently? I've never been very good at biology or chemistry, so I'm turning to you /r/askscience! [link] [comments]  |
| Posted: 03 Sep 2021 07:13 AM PDT The question is simple, what happens when two protons overcome Coulumbs barrier? Do they fuse and make some sort of a hadron? Or do the 2 protons stick to eachother making a sort of nuclei? Or does something else happen? [link] [comments]  |
| Posted: 03 Sep 2021 03:17 AM PDT Is it more difficult to accelerate an object to faster speeds in space like it is on earth? On earth, to go from 20-30mph is much easier than to go from 220-230mph. In the absence of air resistance and engineering limitations, what are the limiting factors, if any, to reaching higher speeds? [link] [comments]  |

| Can removing wisdom teeth change the shape of your face? Posted: 02 Sep 2021 05:20 PM PDT And does each removal change it differently. Like if you removed the lower ones would your jaw shrink and if you removed the upper ones would your cheekbones shrink? How else should the bones heal without absorbing surrounding bone mass.

| Is everyone's digestive tract the same length? Posted: 02 Sep 2021 03:45 PM PDT I mean 2 people who are the same height and size. Does this play into different levels of nutrient absorption? [link] [comments]  |
| What is the actual mechanism behind the symptoms that are caused by trisomy? Posted: 02 Sep 2021 07:16 PM PDT I'm not thinking of any specific chromosome but for example let's say trisomy 21. What is about having a third 21st chromosome that affects the person in that particular way? [link] [comments]  |
| Do large structures inhibit tornadogenesis, such as in urban centers? Posted: 02 Sep 2021 06:48 AM PDT As tornadoes are a rotating column of air that gets pushed toward the ground, would it coming into contact with skyscrapers and other large structures such as a city center cause enough turbulence within the mesocyclone to inhibit or at least weaken a burgeoning tornado? Additionally would a developed tornado hitting a large urban center be significantly weakened as it passed through? [link] [comments]  |
| Could an asteroid theoretically approach the earth so fast it isn't detected? Posted: 02 Sep 2021 02:47 PM PDT Is there a maximum speed an asteroid could travel? And ag that maximum speed could an asteroid approach so fast we would have zero warning of its impending collision? [link] [comments]  |

| Is it possible to build immunity to nettles ? Posted: 02 Sep 2021 04:17 PM PDT Hi I am 15 and living in Scotland I was I get exposed to nettles a ton because I like to go fishing mainly fly fishing at very hard to access places with a lot of nettles today I walked through a massive bush of them and I was wearing shorts my legs were fine but the only stings that hurt were the ones on my hand so did my legs evolve immunity to nettles or is there another reason behind this and also will prolonged and frequent exposure To nettles harm me in any way [link] [comments]  |

| Do humans experience any cycles like the 24h circadian rhythm, but with different frequencies? Posted: 02 Sep 2021 04:16 PM PDT For example, episodic cluster headache sufferers often get episodes cyclically at extremely regular intervals. Each episode may happen once every 90 days, or once every two years (in my partner's case), or at apparently any arbitrary frequency. And within each episode, the headaches may happen once a day at the same time (even almost the same minute), or every 4 hours, and so on - again, the frequency appears to be arbitrary. What could possibly be causing this? Are there multiple cycles of different frequencies in the body which might all "peak" at once, causing a headache? (Knowing cluster headache sufferers and having read quite a bit on it, I do not believe the episodes are somehow psychosomatically induced. The headache results from the activity of the trigeminal nerve, and certain drugs (triptans) and other methods (oxygen therapy in particular) very reliably abort the headaches, apparently by inducing vasoconstriction.)

| Does surface tension get weaker as the temperature of a fluid increases? Why? Posted: 02 Sep 2021 11:51 AM PDT I can't explain this, it just feels intuitive, but it seems to me that the surface tension of a fluid becomes weaker if that fluid gets hot. I'm hesitant to call it a rule or something though because I can't explain it. Is that a real thing, and if so, why does it happen? [link] [comments]  |
