A common example where the median is preferred over the mean is wealth, because the mean gets distorted by a tiny number of mega-rich people.

I'd like to come back to this question - why do microwave ovens make a loud noise?You've had the answer, you just don't want it. The fan makes a loud sound of rushing air, then there's a hum from the transformer and the solenoid around the magnetron.
So far, I haven't seen any convincing answers.
Yes, but that's a hum, not a "roaring noise".It has a large, rapidly varying current running through it, and a magnet wrapped round it.why does the magnetron make a noise?It doesn't. It's a thermionic valve, there are no moving parts.
Since it's not infinitely rigid, it will vibrate.
The power transformer feeding it will also make a noise.
At the time John Maddox's wrote What Remains to Be Discovered, there wasn't even a definition of life, and I don't think there is now either. There are a few words that everyone has an intuitive understanding of, but that are all but impossible to define formally. The dictionary is usually fatuous and circular:AFAIK nobody has ever produced a useful definition of consciousness, so anything approaching an "explanation" is way over the horizon.How do you define "useful"? Is dictionary's definition not useful enough?
Functionally, the brain has a remarkable associative memory compared with any artificial device, but the difference seems to be quantitiative rather than qualitative.
I wondered if evan_au meant AF, but aspirin is no longer recommended for AF as the benefits are minimal, and the bleeding risk is just as high as with Warfarin and other anticoagulants.Atrial fibrillationHowever, some heart conditions can lead to excess formation of blood clots, which could pass to the brain and also cause a stroke or heart attack.Which ones?
Bad capitalism: creating an artificial market for unnecessary crap. Can be harmless (perfume and jewelry advertisements), self-limiting ("art"), mildly dangerous (illegal addictive drugs) or very dangerous (legal addictive drugs).
Good capitalism: bringing useful products within reach of the majority in a competitive market. Generally better than a controlled economy because you can innovate on a whim and the market will eliminate weak products (in principle).
what is best for me conflicts with what is best for everyone?
