I’m glad you’re better now.

So, long term effects might exist as well. If the same mechanics apply long term as well, that would mean that living an active life would make it easier to handle psychological stress.

As far as I can tell, that’s outside the scope of this study. Who knows what the long term effects are. However, it did say this:

Above this threshold, a single bout of exercise induces a cortisol response that is linearly proportional to the intensity at which the exercise is performed.

So the intensity matters in the short run. Take a walk, and it does something to your cortisol, lift weights and it does a lot more.

If you wanted to explore longer term effects, you could just have people exercise regularly for a week or a month and then replicate the rest of the study. I’m really curious about the lingering effect this might have. If you went to the gym every afternoon, will that still help in the next morning when you’re in a stressful meeting?

So if you’ve just exercised, psychological stressors won’t increase your cortisol levels very much? Is that what it’s trying to say?

On the other hand, not exercising means that psychological stressors can spike up your cortisol sky high.

Yes, copper recycling totally works, just like Fe, Al, Pb, Au and Ag. It’s just that the total mass of copper currently in circulation isn’t enough for our ambitious plans. We need a lot more of it to electrify everything. Also, more HVDC lines need to be built, and normally they are made of aluminum, so we’re going to need more of that as well.

Regarding those minerals, Li, Ni, Co and Mn play an important role in electrification, but they don’t have to. It’s just that in recent decades we’ve built the production chains necessary for producing LIBs (Li-ion batteries), and now we’re kinda stuck with that technology. Recently, NIBs (Na-ion batteries) started to become viable, and I really hope they manage to ramp up production quickly. Seems like the author of that article was thinking of LIBs all the time and forgot about NIBs. The problem is, it takes a long time to build the production capacity and production chains.

Then there’s also copper. It’s kinda hard to ignore that one, since we can’t really electrify things when the grid can’t handle the load. Also, electric motors require lots of copper, so I can imagine that the demand for copper will remain high in the coming decades.

Nah, you’re just imagining things.

I guess they noticed that pretty much nobody uses FB any more. It’s mostly just bots and dead people who have that account.
