This article doesn't really make a case in my opinion. The only two justifications seem to be:
> So if a joint doesn’t go through its full range—if the hips and knees never go past 90 degrees—the body says ‘I’m not being used’ and starts to degenerate and stops the production of synovial fluid.”
And,
> A 2014 study in the European Journal of Preventive Cardiology found that test subjects who showed difficulty getting up off the floor without support of hands, or an elbow, or leg (what’s called the “sitting-rising test”) resulted in a three-year-shorter life expectancy than subjects who got up with ease.
> At best, we might undertake ［squatting］ during Crossfit, pilates or while lifting at the gym, but only partially and often with weights (a repetitive maneuver that’s hard to imagine being useful 2.5 million years ago)
I kind of go along with that. Squatting with a bar on your back is a weird maneuver.
Squats under load are pretty fundamental. Carrying a killed deer on your back, or stone, clay, or a mate or a child all require effective loaded squats.
Where is the rest of the movement, then? Why not pick a big bag of sand and place it on your back, walk around with it, and set it back down again?
Wouldn't our ancestors carry far less, maybe max 90kg, then people do today? It doesnt make sense to brutally punish your joints with much more than that for part of that action and completely ignore the other part of it.
Sandbag carries and farmer walks do just that :). As for the idea that you are brutally punishing your joints, I don't believe that to be the case. Controlled squats vs running? Yeah, controlled squats will be way better on the knee. I do weighted exercises regularly and have a marketed reduction in joint pain from before. A barbell squat with good form will not put undue stress on the knee joint and builds muscle that supports it. For me, the added muscle also removed my lower back pain. This also comes with the caveat that you need to stretch and mobilize too.
“Studies have shown that an ant can carry one hundred times its own weight, but there is no known limit to the lifting power of the average tiny eighty-year-old Spanish peasant grandmother.”

> Reality is nobody cares about you in the (semi-)public. Unless you of cause go really crazy.
A few people have been saying that. But, how can you possibly know? It sounds like a platitude one tells themselves in order to not feel self-conscious, rather than an actual discernable fact.
I guess I read this as "as long as you're not disrupting other people/going against the cafe's policies then who gives a shit if other people care about you" more than "other people will never care about you"
Why not kill yourself when you get too old to wash/feed yourself? I'm being serious. I've asked myself that many times and can't find a good reason why not.
It's not even about washing/feeding yourself. I simply don't want to have to work all my life. I'd like to spend my days reading, watching movies, traveling, eating out, etc.
To your question though, I find that as I get older life is increasingly more interesting. I suspect that will be the case regardless of whether I'm hobbled by my body.
Also, if I have grandchildren I can imagine wanting to hang around to see them grow up.
All you did was wave your hands here. What trade off? What subtle disadvantages? What in PoS is weaker than PoW?
You assert these things exist without going into any of them. PoS is very new and complex and there are many differences between implementations, much more than in PoW.
Any dismissal you might have read would most likely been based on a previous version because the latest versions of PoS are quite new.
There doesn't always have to be a meaningful trade-off between different technologies that do the same thing. Is there a meaningful trade-off between a zipped wav file and one compressed with flac?
Please edit such incivility out of your comments here, regardless of how wrong someone else is. The last thing we need is flamewars about who's fudding.
It doesn't matter if you own crypto or not. The mere existence of it creates a threat for every relatively rich person out there. They can simply coerce your family to buy bitcoin and give them some, on threat that they kill you.
I'm sure it's not impossible to find 'under the radar' rich people - and people who take care to not flaunt their wealth will probably be more likely to try and make the whole thing go away quietly by paying up.

As far as the first one, I'd say, so what? More fluid means healthier? Why?
As far as the second one, correlation doesn't prove causation. We should stop pretending this is the case with everything.
