Opinion | The Utter Uselessness of Job Interviews
April 16, 2017The Utter Uselessness of Job Interviews
https://www.NYTimes.com/2017/04/08/opinion/sunday/the-utter-uselessness-of-job-interviews.html Random answers work better for interviewees than correct ones HT @shantaolee

“It gets worse. Unbeknown to our subjects, we had instructed some of the interviewees to respond randomly to their questions. Though many of our interviewers were allowed to ask any questions they wanted, some were told to ask only yes/no or this/that questions. In half of these interviews, the interviewees were instructed to answer honestly. But in the other half, the interviewees were instructed to answer randomly. Specifically, they were told to note the first letter of each of the last two words of any question, and to see which category, A-M or N-Z, each letter fell into. If both letters were in the same category, the interviewee answered “yes” or took the “this” option; if the letters were in different categories, the interviewee answered “no” or took the “that” option.”

Baths Versus Exercise, a Study in Calories – The Atlantic
April 16, 2017Baths vs #Exercise, a Study in Calories
https://www.theAtlantic.com/health/archive/2017/04/baths-and-calories/522756 In 1hr, burn 60 in a hot bath vs ~550 on a bike ride. Laziness has benefits!

The researchers set out to see how exposure to heat can alter the molecules in our bodies. There were only 14 people (all men) in the study. They took hour-long baths at 104-degrees Fahrenheit and did burn calories, which were also measured, since energy is required to keep our cores around 98.6-degrees. But the men only burned an average of about 61 calories more than if they had been sitting at room temperature. When they exercised on a bike for the same amount of time, they burned between 515 and 597 calories.

THE BRAIN FROM TOP TO BOTTOM

The stimulant effect of coffee comes largely from the way it acts on the adenosine receptors in the neural membrane. Adenosine is a central nervous system neuromodulator that has specific receptors. When adenosine binds to its receptors, neural activity slows down, and you feel sleepy. Adenosine thus facilitates sleep and dilates the blood vessels, probably to ensure good oxygenation during sleep.
Caffeine acts as an adenosine-receptor antagonist. This means that it binds to these same receptors, but without reducing neural activity. Fewer receptors are thus available to the natural “braking” action of adenosine, and neural activity therefore speeds up (see animation). “}}
Serotonin: Facts, What Does Serotonin Do? – Medical News Today

It is thought that serotonin can affect mood and social behavior, appetite and digestion, sleep, memory and sexual desire and function. …
Drugs that alter serotonin levels [SSRIs] have important clinical uses such as in the treatment of depression, nausea and migraine. …
Serotonin is created by a biochemical conversion process which combines tryptophan, a component of proteins, with tryptophan hydroxylase, a chemical reactor. Together, they form
5-hydroxyltryptamine (5-HT), also referred to as serotonin.
Serotonin is most commonly believed to be a neurotransmitter, although some consider the chemical to be a hormone.
…
t is believed that medication such as selective serotonin reuptake inhibitors (SSRIs) that can affect the levels of serotonin in the body work as antidepressants and are able to relieve the symptoms of depression. It is unknown precisely how they work, however.
