Oh, I really like this idea. I might go with a number greater than two though for the aesthetic reason that 25% of the time, you will select a song that has been played more recently than half of the playlist. With four, you'd be selecting something from the back half of the playlist more than 90% of the time.
There is humor in the disparity between the resources and people marshalled to resolve the issue (including Bill Gates himself) and the humble origin of the issue, a shower curtain.
The self-incrimination clause was motivated by the practice of forced confessions, which were elicited by threats, indefinite detention and torture. You can get a DNA sample with a cotton swab, but it takes much worse to extract information from someone's mind.
It's not only because of the amount of force used. It's also because of the power it gives to the police.
If they had a mental scanner that allowed to get information out of people's brain without keeping them in jail forever or torturing them, it still be a problem - because without controls on it what the police would do is just round up everyone looking suspicious enough, brain-scan them en masse and use all the information gathered. And of course they would claim "if you're a honest man, you don't have a reason to be concerned".
So it's not only about torture & detention, it's about not giving police the power to own any information they'd like to have just because they want it. We have "due process" because police and state power is huge even as it is, without strict controls on it a private citizen has very little chance to resist any abuse and to correct any error.
Wow, norms change quickly. I traveled with my golden retriever several times last spring (always asking first by phone) and the drivers were all genuinely surprised when I offered a tip at the end of the ride.
The amount of competition in the beer world is just incredible. (I just checked with a beer-enthusiast friend and he tried over 1000 different beers just in 2016.) To get people's attention and then to maintain a reputation as a great beer for several years, a beer has to be more than just an extreme example of a certain style. No doubt, though, the ambition to be interesting to aficionados of a given style does push certain beers towards the extreme. These beers are not bad, just niche in their appeal.
There is truth in what you say about the psychological value of scarce beers. However, being hard to acquire cuts both ways in a world of so many alternatives: the beer enthusiasts that I know are quick to dismiss a beer as not worth the effort after one sip.
It's not necessary in any real sense, but a foul-mouthed astronaut who doesn't swear isn't a foul-mouthed astronaut. It's a trait that works well with the character's irreverent attitude.
