Anything Goes On Sunday: People Excercise In Venice Beach Homeless Nightmare Please Watch Video
I don’t understand how is it that cyclists, joggers, and runners are exercising in the middle of so much filth. It cannot be healthy to be breathing that air, seeing that kind of trash, rats, and feces of the homeless people.
I would definitely NOT ride my bike in any place like that ever. We shouldn’t get used to practicing our favorite exercise in the middle of that kind of environment.
When we practice a sport, we have to take care of our physiological, anatomical, and mental functions. We need to take care of our well-being. And we shouldn’t get used to seeing people living in squalor, becoming desensitized.

The human body never ceases to amaze me. The more I learn, the more I wonder, the more questions have to be asked and more research to do. I just adore the human body: its physiology, chemistry, pharmacodynamics, anatomy, biology.
Studying medicine is never-ending and has always been an honor and a scientific privilege from which I am deeply humbled.
Learning Wednesday: Science Knowledge And Wisdom
Learning science, practicing it, understanding it, loving it! I also cherish many scientists who have given us the pleasure of expanding our way of living and our mental horizons and who have worked tirelessly to better humanity. So here there are some quotes from one of the so many scientists that I deeply admire.
«The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.» — Isaac Asimov
«I am not a speed reader. I am a speed understander.» — Isaac Asimov »
«There is a single light of science, and to brighten it anywhere is to brighten it everywhere.» — Isaac Asimov
«Suppose that we are wise enough to learn and know – and yet not wise enough to control our learning and knowledge so that we use it to destroy ourselves? Even if that is so, knowledge remains better than ignorance .» — Isaac Asimov

Everything Goes On Sunday: Rare Images And What Not
This was way before Google Earth. This photo was the first ever to be taken from outer space, showing planet Earth through the lens of a 35-millimeter camera that was attached to a missile. This first picture of Earth from space was taken in 1946 aboard a V-2 rocket, but it was grainy and barely recognizable as Earth.
This gas-proof carriage was designed after the British were afraid that Nazi Germany would poison the population with a toxic gas attack.
From 1920-1933, Alcohol was banned in the United States. Before that, beer and all that was legal so you can imagine the disappointment of these men when alcohol was taken away from them! Riots, hahaha.

One of my Many Pet Peeves: Troop vs Trooper or Soldier Part 1
English is not my native language, Spanish is. I also speak Italian, Portuguese and I am fluent one hundred percent in all these languages. But I admit that I make typos and several mistakes when I write in my non-native languages, but I always try to learn and speak better, even in Spanish and I am always willing to learn from my mistakes. That is why I am a serious critic of misconduct in expressions in the languages mentioned above.
So here it goes, my pet peeve of today: Troop VS Trooper
I often hear reporters on American TV channels talking about «troops». The first time when I listened to that word being misused was when the war in Afghanistan was being announced by different TV reporters back in October 2001.
They were mentioning the amount of «troops» that President George Bush was sending. I was astonished! They said ten thousand of them were parting from the USA. So I started to make my own calculations and said well, if a troop has a minimum of 3 to 5 platoons;
One platoon has 2 to 4 squads, and each squad has 10 to 14 troopers or soldiers, then a platoon has about 50 soldiers, then a troop has a minimum of 250 men. If President George Bush was sending 10,000 troops then he was sending about 2, 500,000 (two and a half million) soldiers or troopers!
And next week they said more «troops» were leaving for the Middle East. By then I knew how erroneous and non-well educated in their own language they were: when they were saying «troops» they were referring to a singular, to one man, which is wrong.
For some English speakers, a “trooper” is a mounted soldier. For others, a “trooper” is a policeman who patrols the roads of a U.S. state in a car.
As to “how a plural word becomes singular,” the answer has to be “by being used that way.”
However, just because usage is widespread or has been added to a dictionary doesn’t mean that it is worth adopting.
