From the Nebula Award-nominated short story, “They’re Made Out of Meat” by Terry Bisson:

“They’re made out of meat.”

“Meat?”

“Meat. They’re made out of meat.”

“Meat?”

“There’s no doubt about it. We picked up several from different parts of the planet, took them aboard our recon vessels, and probed them all the way through. They’re completely meat.”

“That’s impossible. What about the radio signals? The messages to the stars?”

“They use the radio waves to talk, but the signals don’t come from them. The signals come from machines.”

“So who made the machines? That’s who we want to contact.”

“They made the machines. That’s what I’m trying to tell you. Meat made the machines.”

“That’s ridiculous. How can meat make a machine? You’re asking me to believe in sentient meat.”

“I’m not asking you, I’m telling you. These creatures are the only sentient race in that sector and they’re made out of meat.”

A little while later:

“They actually do talk, then. They use words, ideas, concepts?”

“Oh, yes. Except they do it with meat.”

“I thought you just told me they used radio.”

“They do, but what do you think is on the radio? Meat sounds. You know how when you slap or flap meat, it makes a noise? They talk by flapping their meat at each other. They can even sing by squirting air through their meat.”

“Omigod. Singing meat. This is altogether too much. So what do you advise?”

“Officially or unofficially?”

“Both.”

“Officially, we are required to contact, welcome and log in any and all sentient races or multibeings in this quadrant of the Universe, without prejudice, fear or favor. Unofficially, I advise that we erase the records and forget the whole thing.”

“I was hoping you would say that.”

“It seems harsh, but there is a limit. Do we really want to make contact with meat?”

“I agree one hundred percent. What’s there to say? ‘Hello, meat. How’s it going?’

Can stress really help you do better and if so, how much is the right amount?
Ultimately stress is a way for your body and mind to communicate impending needs or events which require attention. Once you have recognized and acknowledged the message, there should not be any need to… stress over it.

“…having some stress helps my decision-making, because it helps to maintain a focus on the situation,”

“…Too much stress causes what we call cognitive overload and then impairs your ability to make decisions because you’ve lost that situational awareness,”

“…stress is really importantly implicated in performance and in health,” “It’s very helpful for legitimate emergencies, and to achieve peak achievement in high-performance events.”

“…in physiological terms, (stress) arousal might take the form of an increased heart rate, redirected blood flow to the brain and large muscle groups, and release of glucose to act as fuel. The body’s resources are reallocated to be most useful for an emergency, from greater mental alertness to higher muscle tension. The brain and body are essentially bracing themselves.”

“While the Yerkes-Dodson principle appears to resonate with many, there has been plenty of criticism of it too. Detractors suggest it is applied too broadly. For instance, some people may be galvanised by pressure because they’re “defensive pessimists” who perform better when they worry a bit. Others find positive reinforcement more motivating. Sleep deprivation might harm speed, but not accuracy (so a sprinter shouldn’t stay out late every night). Noise might hurt accuracy, but not speed (so a reporter should try to find a quiet space).”

“…any stress can cause (extreme) harm when it’s prolonged. To take just one example, a chronically high heart rate is linked to cardiovascular risk.”

“One key factor is to avoid, where possible, the tipping point when stress leads to burnout. Burnout, with its physical and mental harms, is especially likely when stress is chronic. ”

“Another factor is the presence of control. For those who feel powerless over their situation, stress is unlikely to be beneficial.”

“Studies show that acute, uncontrollable stress limits the functions managed by the prefrontal cortex, which is responsible for working memory. So the test-takers should try not to deplete their precious working memory by worrying, and the athletes should focus on outcomes (e.g. where the ball should be going) rather than on their bodies.”

“When it comes to stress and how it affects your performance, it’s helpful to recognise the variations in personality, type of stress and task that affect where you sit on the bell curve, as well as understanding tools you can use to control or harness that stress.”
