On a tangent note: don’t use ultrasonic humidifiers. Unless distilled water is used, they create a shit-ton of pm2.5 particles. Use evaporative humidifiers (just disks with myriads of small notches for water to cling on and a fan): https://us.smartmiglobal.com/pages/smartmi-evaporative-humid...

The best solution I've found a few years ago is one Venta LW 45 for every 30 m² of space. That's enough to run them on the lowest speed while maintaining acceptable humidity and CO₂ levels. Higher speeds are too noisy. Smaller machines evaporate less. For sub-zero outside temperatures, it's necessary to add at least 5 g of water to each cubic metre of air coming from outside. The recommended ventilation rate of 30 m³…
A humidifier needs network capability incase someone discovers a new version of water, or for the manufacturer to be able to patch remote exploits. https://xkcd.com/3109/
I'm all for KISS. But in a rare instance, xkcd is missing the point here. People do not live in their rooms 24/7, but they do want to be able to, e.g., turn stuff on or off remotely, or based on environmental conditions (turn on/off based on outside sensors or the current electricity price...) or to get status alerts ("tank empty, refill"). Now, I do that via Home Assistant and keep anything "smart" on a highly-restr…
> turn stuff on or off remotely
Why? Nearly all modern humidifiers have a sensor to measure humidity and will cycle on and off based on the setpoint. Getting to the setpoint also takes time so I don't see any reason someone would want to turn it on and off based on presence.
> (turn on/off based on outside sensors or the current electricity price...)
Not sure why the outside sensors would matter, it's concerned with the inside humidity which again it has a sensor to read. The amount of electricity these take to run isn't worth even mentioning.
> get status alerts ("tank empty, refill")
So you can refill it remotely? You have to be present to fill it anyway - just look at the thing and you'll know its water level
I say all this as someone who also run Home Assistant and automates various things.

> On a tangent note: don’t use ultrasonic humidifiers. Unless distilled water is used, they create a shit-ton of pm2.5 particles. Not according to my uHoo air quality monitor. I have had one running a few feet from the monitor for over a week and there hasn't been any notable increase in PM2.5 particles.
In the next room (where there were none) it was 6.
Depends on the water, I guess.

Distilled water isn’t strictly necessary. I use mine with purified water with a reverse osmosis purifier. I periodically test the TDS of the water to confirm it is low. It’s fine.
Especially evident on some black leather bags in the wardrobe.
Tangential rant: It’s becoming hard to buy dumb appliances. I was looking at robot vacuums, and most need internet connection at least for setup - by which point it’s already uploaded your floor plan and who knows what to the cloud.
Not sure that’s a great example when you can easily buy a regular vacuum. Robot vacuums are sort of by definition already the “smart appliance” version of the “dumb appliance regular vacuum”.

> any notable increase in PM2.5 particles What's your PM2.5 baseline, and did you measure TDS in the water?

That’s a lot of refilling. You might want to look into a whole house humidifier, I added an aprilaire 700 evaporative to my hvac ducts, it costs a few hundred $. Plumbed in, automatic. So much less screwing around

> Use evaporative humidifiers You don't have to buy one either. A suspended wet towel with a fan blowing on it will work very well. If you want to get fancy, have the last inch or two of the towel sitting in a tray of water.
That's a permanent bachelor design aesthetic.

Eh, here it's more of a simplification than a myth as used in my comment. There are two effects: 1. We've reduced infant (and childhood) mortality. My comment isn't talking about this effect but it did drag down average life expectancy substantially. Including this effect life expectancy at birth in the stone age might have been as low as 20... but as you say the bimodality means this is a deceptive statistic when us…
The age 40 includes childhood mortality! It's difficult to get records from prehistoric humans for obvious reasons, but as early as Ancient Greece you had the upper class living about as long as we do now a days. A study of men of the time found the average life expectancy to be 71.3 years. [1] And while the Bible includes plentiful mythological components, it also includes many historical and contemporary accounts.…
Which translation is that? Or are you paraphrasing?
Most translations don't include "generally," and therefore read more as an upper bound "if one is strong" than an average.
