By use of meditation and yoga I've found the opposite to be true. The system I've used is described somewhat here http://isha.sadhguru.org/blog/lifestyle/health-fitness/10-he... Edit: downvotes why?

I didn't down vote you,but just skimming through your article, #9 seems false. Blood is not affected by magnetic fields, it seems to me. https://www.quora.com/Why-isnt-blood-attracted-to-a-magnet-s...

I can't attest for that point scientifically or even personally.

The argument in #9 as I understand it is, over the course of your lifetime, the cumulative minuscule effect of how you sleep relative to the Earths magnetic field can have a negative effect on your health, increasing the risk of stroke or brain related conditions.

To prove or disprove would require long term study (in the order of a human lifetime) with equipment capable of detecting very small changes while eliminating all other effects.

I didn’t downvote you but claiming meditation and yoga substitutes for sleep pattern matches to quack/idiot. Your link has the word guru in it which points the same way. Personally I find it credible because I’ve read studies before suggesting meditation can substitute for sleep 1 for 1 up to some threshold but I’m too lazy to search for them. If you make claims that are as credible as a homeopath or anti-vaxxer cite…

Fair enough. Was in a hurry. Was obviously a topic that needs more detail. Have also seen those studies (via HN) - in fact they were what originally got me curious about meditation about 5 years ago.

Meanwhile the guru in question is one that gets invited to Talk at Google, if that's any measure of credibility - https://www.youtube.com/watch?v=QQn8X4FbpTM

Maybe. But do parents think they're protecting kids by driving them instead of letting them take the bus? They're going to get bullied mercilessly as soon as they get to school anyway. School is simply a horrific hellhole for the bottom 20% of kids. People just like to feel like it's not. And unfortunately "bottom 20%" can happen to anyone -- it's not merit-based. More like affluence-based.

> But do parents think they're protecting kids by driving them instead of letting them take the bus? They're going to get bullied mercilessly as soon as they get to school anyway. Not a parent but I wouldn't expect to drive children to protect them from bullies but child kidnappers or other random dangers. I'm pretty sure that's why my parents drove me too.

Is that stuff really a concern? How many random child kidnappers are there? Don't children go out to play? And then walk home alone from wherever they hung out? I thought Stranger Danger was sort of a joke for many areas now. Especially considering people on HN are usually middle class at minimum.

I never had any issues walking to the bus stop starting in kindergarten. Though granted I almost never walked alone. Usually with a friend or two.

I'm in a much more affluent place now. I see parents walking their kids to the corner of the street of our housing complex. Seems a bit extreme to say the least.

Honest question: Why do people do this with the school pickup/dropoff? What is the point of that? Do schools still have buses?

When I was in school (90s and early 2000s), it would have been considered extremely embarrassing to have your mom drop you off and pick you up every day. I think it was about the time I graduated that things began to shift. When I was in elementary school, the was nowhere for parents to pull up curb-side and get the kids. By the time I finished high school, the elementary school had blocked off half the curb-side int…

Hah, even more so it was embarrassing to have your parents walk you just to the bus stop for me especially after 2nd grade (which was what separated our early and middle elementary school). Roughly same time period of school. We also only had one bus stop for a pretty big multi-hundred apartment complex.

Things do seem to have changed now. Or it's just that I moved. Not sure.

15h / 5 days is 3h / day -- 1.5 hours each way, that's a long commute. The average commute in the US is 20 min each way. Suburbanites mostly jump to nearby suburbs. It's the urbanites & rurals who outlie, with interminable train rides or stops-and-gos via SUV & long highway drives to a bigger town an hour away. A map of US commute times: https://lifehacker.com/this-map-shows-the-average-commute-ti...

I did this for six months. I live in NH, I got a well paying contract in MA, and they needed me to work 60 hrs/week to rescue a project. The 60 hrs/week is key, because it made the ratio of billable hours to wasted hours plausible - 15 hours of commute to 40 of billable is terrible, but 15:60 made some sense. Those six months (plus the side remote consulting gig I did on the weekend) almost killed me, but they also l…

Would you do it again if something awful happened and you all of a sudden were in the same spot you were when you did that work (less or none of your mortgage paid off or something). Just wondering. Seems like it sucked but worthwhile if it paid off 1/3 of your mortgage. Good job!

Once they got old enough, sure. Until then, women typically took care of them. Good luck working alongside an 18 month old.

Yeah, it's like trying to work in an open office, with people repeatedly stopping by with problems, and springing surprise meetings, and... well, maybe not quite that bad? :)

I'm not sure what's scarier: a coworker stopping by saying, "hey, the PROD-DB-1 server has been down for four hours" or your four year old stopping by and saying, "there's an oops in the kitchen."

Actually, studies have shown that hunter-gatherer societies spent much less than 40h/week "working" and had more leisure time than we do. It's just recent history that's an anomaly...

As the technology advances we should be working less but its the opposite. Here's an essay by Bertrand Russel http://www.zpub.com/notes/idle.html

Great essay. Bertrand Russel never ceases to amaze. For others, the essay is titled In Praise of Idleness, but is about using your idle (non-working time) for pursuits.

Not to turn this into something else, but pursuing things during "idle" time is another reason why if reasonably possible, basic income could be great alongside more advancements like automation occurring.

Bear in mind that we segment our activity more in "modern" society. For example, in agrarian societies you didn't need to carve out time for exercise. Work was exercise. You also didn't need to carve out time for child care, because children worked alongside adults much of the time. And commuting wasn't really an issue when workplaces and residences were in the same community with minimal geographic separation. It's…

I wonder how VR/AR will change this? With your four display setup, now perched on your nose, moving between sitting desk, standing desk, and stretching on the floor, means moving a wireless keyboard. And for tasks where phone-like keyboards are good enough, no need for the desk, just wander. Twitch a finger on a pad, twitch a hand and arm on mouse or controller or knee, or raise your arms and dance. You, not the task…

I can't tell if your VR-parenting suggestions are tongue-in-cheek or not. I'm terrified either way.

What studies? This is the internet, use that fancy hypertext. I'm not very familiar with this particular area, but I do know from books like The Better Angles Of Our Nature (and criticisms thereof) that this is a contentious statement. There are many myths about ancient humans, some that overly indulge in 'savagery' and others that are too idyllic. The evidence for either interpretation is fairly fraught and I'm deep…

Yeah getting some studies and info on this would be great.

Later, in 1996, Ross Sackett performed two distinct meta-analyses to empirically test Sahlin's view. The first of these studies looked at 102 time-allocation studies, and the second one analyzed 207 energy-expenditure studies. Sackett found that adults in foraging and horticultural societies work, on average, about 6.5 hours a day, where as people in agricultural and industrial societies work on average 8.8 hours a d…

Thanks. Not about humans of the past, but still a relevant study.
