This box cutter tool, which is https://a.co/d/aOxoVOp . It makes opening packages so much easier. It doesn’t have a blade, so it’s much safer to use than scissors or a knife.

#162Philips Sonicare 7300 electric toothbrush - this thing is awesome, every time I brush my teeth they feel super clean and smooth like porcelain. $149 one of the best purchases I ever made. https://a.co/d/2fFJgow Another product that improved my life is AirPods, if you’re into the Apple ecosystem they’re worth every penny.

cracking everything wide open for 5 minutes doesn't have too bad of an effect on temperature in my experience, and gives you good air for a few hours.
My home has very poor ventilation so I periodically will open the windows and blast a box fan to "flush" the dirty air out. If done quickly, there's not much thermal loss.

#164Flow Club. Hands down the best thing I've ever done in my life.

#165A Nutr machine so I can make quality nutmilks at home instead of buying store bought stuff loaded with nasty preservatives and very few nuts per serving.
Do you do oat milk? Wondering if these devices avoid the gel-like consistency that forms when I make it in my blender.

CO2 poisoning is very common. It leads to fatigue, headaches/migranes and concentration issues. Most people don't recognize it and try to cope with caffeine & pain killers. I noticed that sitting in a tightly closed office surrounded by monitors , CO2 was being trapped around me . I started testing with blood oxygen monitor and could reliably predict low blood O2 based on the above symptoms. tl;dr keep your door and/…
It's important to note these two issues (high CO2 and low oxygen) only go together in the most extreme scenarios and CO2 can be impactful long before O2 levels noticeably decrease or start affecting your blood O2 levels. For CO2 to be extremely high and causing headaches, dizziness, and nausea it's around 0.1% to 0.2% (more often represented as 1,000 to 2,000 ppm due to the low typical concentration of ~420 ppm globa…
It's important to note these two issues (high CO2 and low oxygen) only go together in the most extreme scenarios. CO2 can be impactful long before O2 levels noticeably decrease or start affecting your blood O2 levels. For CO2 to be extremely high (causing headaches, dizziness, and nausea) it only needs to be in concentrations around 0.1% to 0.2%, more often represented as 1,000 to 2,000 ppm due to the low typical concentration of ~420 ppm globally. On the other hand, air is 21% oxygen (by volume) and at 10x the difference of 1%/10,000 ppm less than normal the air is not even considered oxygen deficient yet.
While I'm writing this comment, it's important to note you will almost certainly notice high CO2 content in your environment but you very likely won't notice low O2 content until it's well too late. Think about inhaling a helium from the balloon tank. You know there is very little O2 in it at all, you can even hear how it changes your voice due to the displacement, but you can keep breathing more in and out until you pass out cold and not even "sense" the lack of O2 until seconds before that moment when you feel lightheaded or your vision starts to fade. On the other hand if you breathed in CO2 like that you'd immediately notice and feel absolutely awful. This is because the body doesn't detect how much O2 you're taking in it detects how much CO2 you're able to get rid of. All this is to say, if you have low blood O2 levels don't necessarily expect to be aware of it.
The third thing I'll mention, since it seems to inevitably come up, is "CO2" (carbon dioxide) should not be confused with "CO" (carbon monoxide). CO and CO2 are very different things with different ppm values of concern and different outcomes when they are out of range. CO will kill you in less than an hour at 1000 ppm with effects from long term exposure possible at far less than that. If you have an appliance that burns fuel to function you really should have CO detectors, even if your state/goverment doesn't mandate one. If you don't get a CO2 monitor the worst that'll happen to you is you'll not feel as great (assuming CO2 isn't so bad your problem is actually there isn't enough oxygen left).

#169MaxiNutrition Hydration Tabs. Much easier to drop into a glass of water than powder-form electrolytes (no messing around with a spoon etc). Also something to keep in your pocket/bag on a longer bar night. I can't guarantee the nutritional value being a nonexpert but at least the convenience is great.

#170A set of nice flashlights. Why walk around in the dark? Some that I like: Sofirn SP36 BLF, LT1, SC21, HS10. Wurkkos TS10 (and I’ll be getting a TS11 soon.)
Love my hexbright. If they were still being made, I'd get more.
