Hydrochloric Acid Production... of the Stomach

Real knowledge is to know the extent of one's ignorance. - Confucius

To start off with Hawking's quote, "The greatest enemy of knowledge is not ignorance, but the illusion of knowledge". Many people being in such illusion, try to be a 'hero' at the cost of pulling others' legs. They feel themselves superior by mocking at others, there by proving themselves to be that empty vessels, which alone make much noise. Any person who has touched the surface of knowledge, will be very afraid, as the more you know, the more you realize the realms and extent of ignorance. About all those people who pull others' legs, make fun of others, regardless of others' age (mocking people who are elder to us), experience etc., are mere 'fools'.

मूर्खस्य पञ्च चिन्हानि गर्वो दुर्वचनं तथा।
क्रोधश्च दृढवादश्च परवाक्येष्वनादरः॥
---
These are the five signs of fools - Pride, abusive language, anger, stubborn arguments and disrespect for other people's views.
---
As the sun destroys the darkness, the sun of knowledge, knocks the fools, and demolish their kingdom.
---
While the laughter of joy is in full harmony with our deeper life, the laughter of amusement should be kept apart from it. The danger is too great of thus learning to look at solemn things in a spirit of mockery, and to seek in them opportunities for exercising wit. - Lewis Caroll.

Decompression Sickness

As we’ve already seen, the low pressure of space prevents oxygen fromremaining dissolved in your blood. This vacuum-like environment does the same for other gasses, like nitrogen. This causes tiny nitrogen bubbles to form all throughout your circulatory system (which is the literal definition of the bends). One side effect these bubbles have is extreme joint pain, but far worse are the effects the bubbles have when they create blockages in your veins and arteries. Bubbles in your brain can cause stroke and seizures. A bubble in your heart can cause sudden heart failure and death.

No Blood Pressure

As you can tell by now, space has horrible effects on the human body. Both internally and externally, you are stretched, ballooned, and otherwise contorted. As a result, your misshapen body will struggle to maintain anormal blood pressure. For example, a person can easily generate enough force to drink soda through a normally sized straw. But what if the straw’s diameter was 10 times as large? Similarly, your heart would not be capable of pumping blood through your enlarged veins. Your blood pressure would effectively drop to zero and you would die.

Boiling Blood

The lower the pressure is in an environment, the lower the boiling point will be for any liquid in that same environment. This is because when there’s less pressure, it’s easier for the molecules to move around, so it takes less heat energy to transform the packed-in molecules of a liquid to a less-dense gas.

This is why water boils more easily at higher altitudes. In space, the boiling point of your blood could realistically drop down until it’s the same as your own body temperature—at which point your blood would begin to boil. The temperature of your blood would still be normal, but in the vacuum of space that might be all it needs to boil.

Suffocation By Hypoxia

When exposed to the vacuum of space, a person will be totally deprived of oxygen, but not in the way you might think. The condition is known ashypoxia: Without earth-like pressure, the oxygen in your bloodstream will begin to reverse-dissolve and escape from your blood. This will render your cardiovascular system useless, and no oxygen will be delivered to your muscles or vital organs. The fact that you are no longer able to breathe in any new oxygen just exacerbates the problem. In addition, the suffocating effect would begin to turn your skin blue. A person can last approximately 10 seconds in this condition before they black out.

How to give killer presentations...

“We all know that humans are wired to listen to stories, and metaphors abound for the narrative structures that work best to engage people. When I think about compelling presentations, I think about taking an audience on a journey.”

“Many of our best and most popular TED Talks have been memorized word for word … Most people go through what I call the ‘valley of awkwardness,’ where they haven’t quite memorized the talk. If they give the talk while stuck in that valley, the audience will sense it … Getting past this point is simple, fortunately. It’s just a matter of rehearsing enough times that the flow of words becomes second nature.”

“Perhaps the most important physical act onstage is making eye contact. Find five or six friendly-looking people in different parts of the audience and look them in the eye as you speak. Think of them as friends you haven’t seen in a year, whom you’re bringing up to date on your work.“
