it does provide rotational stability (along with the PCL, between the femur and tibia; the condyles help here too) but it’s primarily job is lateral stability in the front-to-back direction, because without that, you cannot negotiate uneven terrain at all. this is vividly illustrated in a dissection by manipulating the knee with and without cutting the ACL. with no ACL, the knee is a wobbly mess, especially in the front to back (ventral-dorsal) direction.
ACL injuries have long been known to be worse in women because of anatomical differences in weight distribution relative to hip to femur to tibia angles, both statically but especially in motion.
it's less about what foods to eat and more about eating much less: one modest-sized meal a day. that's all we "need". we eat too much of everything and our bodies are not evolved for such excess. this is literally the biggest bang for buck for chronic diseases like this, but also the hardest thing to do because of socio-cultural considerations. it also takes some time to train your digestive system down to that level.
once you have amounts under control, then you can taper off the processed foods, especially sugary things like soda/juice (fruit is ok because it comes with fiber), salty things like chips/frozen dinners, and bread/rice products (a little whole grain here and there is ok). minimize processed foods but don't worry too much about the mix of foods otherwise (protein/fat is fine, just don't overeat).
then taper up anaerobic exercise to 2-3 times a week. find a sport or activity you like (e.g., tennis) and pay for an organized league/class so that you stay committed. (aerobic) walking, for instance, is not typically strenuous enough for your body to process the excess nutrients and improve cardiovascular fitness, which is what's needed to help keep heart disease under control. you can start with walking if you're in bad shape, but you'll want to graduate to anaerobic exercise as soon as you can.
no one should worry about CO₂ at all in their homes or offices. only workers in certain industries/factories, where CO₂ can get several orders of magnitude higher, need to be concerned at all about it. you (here and in your marketing materials) are stoking needless anxiety over a gas that life on earth literally requires.
pollutants, on the other hand, and particularly particulate matter (especially chemicals that we've manufactured recently in human history), do have proven negative health consequences and should be monitored and mitigated in the home and office. it's estimated that over a million people a year die prematurely of respiratory and cardiovascular complications due to pollution.
in short, a lack of CO₂ monitoring in favor of PM and VOCs by ikea should be seen as a plus, not a minus here.
I thought cheap instruments usually estimated CO2 from a MOS TVOC sensor.
In any case, for automation purposes, CO2 sensing is extremely useful. Regardless of whether you think indoor CO2 directly causes cognitive performance issues or is a proxy for other things that cause those issues (the issues themselves are well documented), indoor CO2 is an excellent measure for the fraction of indoor air consisting of exhaled air, which is a good thing to use for automated demand controlled ventilation.
Not at all. The majority of studies have found a notable decline in cognitive ability starting somewhere around the 800-1,200 ppm range. Due to increasing insulation/energy standards/etc, modern homes have poor air exchange and levels will often get that high or higher unless a window is opened. I have seen quite a few reports of people seeing levels exceeding 2,000 at night, and multiple studies showing that many multifamily/efficiency homes would easily get over that 1,000 ppm mark.
now that physical branches are not really a differentiator of big banks, a couple hours of your time spread out over a couple months is totally worth the switch to a credit union in lower fees, better service, and supporting a more local economy.
it's completely, undeniably worth it. unless you're a real big shot (worth millions in assets to the bank) who doesn't have to deal with the dehumanizing aspects of corporate "customer service", there is zero reason to be with anything other than a small local bank/credit union.
I don’t think the issue is their customer service not being helpful it’s just that the bank is so predatory. Things like high fees ($10/month) for checking accounts being below a threshold or opening up bogus accounts for people.
i've played with nesting on firefox and, much like the :has() selector, it seems good enough for the 80% case, so i wish they'd unflag it so we could get the clock started on having it be commonplace in a year or two to use it confidently.
safari and chrome have had :has() for a while, but it's behind a flag in firefox. the firefox version is good enough that i wish they'd unflag it already (as in, it's good enough to handle this particular input/label issue for instance, but not really complex selector combinations and edge cases).
real world boston was the only reality tv show i watched more or less all the way through. it was fun while it lasted but once it was over, reality tv felt "done" and i didn't really want to watch much more of it. i still don't understand the lasting appeal tbh.
instead you get to breathe in that sweet, sweet tire dust, which hybrids and EVs tend to make more of because they're typically heavier than their ICE counterparts.
but until the electrical grid is moved to cleaner sources (including nuclear for baseload), it doesn't make much difference what you drive. with the current distribution of generation, we'd be mostly shifting the pollution from tailpipes to smokestacks (especially at the margin) rather than getting rid of it--coal emissions are many times worse than tailpipe emissions, not to mention the pollution from coal, oil & gas extraction.
and pollution is exactly what we should be worried about, not CO₂, which is the worst sort of distraction when trying to make sense of the environmental dangers we're creating (it muddies the waters to create uncertainty and inaction).
> coal emissions are many times worse than tailpipe emissions
The CO2 output of a coal powered EV and a gasoline car are roughly equivalent. If you add in the CO2 used when refining the gasoline and when transporting the fuel to gas stations, gasoline cars are about 50% worse.
> and pollution is exactly what we should be worried about, not CO₂,
For most pollutions, especially for PM2.5, locality is super important. Gasoline engines run in populated areas, power plants aren't.
again, CO₂ doesn't matter, despite the mediopolitical hysteria over it. it's a gas that life depends on and is well-adapted to. but pollution has been killing millions of people a year for at least a hundred years already and will continue to do so for the foreseeable future. generation and transportation account for the majority of that pollution.
