MD, PhD, but still trying to figure out life…

Nowadays, being happy seems one of life´s big quests. Goodreads quotes give an astounding 15,238 hits for quotes about happiness. And people try hard to do whatever makes them happy, even if they don´t really know what makes them happy. Social media is also a big promotor of the happy life, and people love to show off how happy they are. However, if we look at real life, we see that it is not easy for people to be happy, not to mention that seeing happy friends on social media while you are not happy can make you even less…

I am not a conspiracy theorist, and the idea that COVID-19 was man-made at the start of the `pandemic´ in 2019 sounded too far-fetched to me. But we always have to be aware that we are under the influence of cognitive dissonance, the media, or simply the fact that we can be wrong and do not know everything. Currently, more and more data is coming out, which should make us rethink and take the idea that COVID-19 is man-made serious.

How Did the Pandemic Start?

How the pandemic started is important because it shows how the Wuhan Institute of Virology is involved. In November 2019…

NASA released new pictures from NASA´s Curiosity rover. I was amazed by the beauty, and I want to share this with you.

On Earth, in most regions, we are used to clouds; they consist of water and can have all kinds of shapes, often leading to just staring at clouds and fantasizing about what we can see in them. They are an essential part of the water cycle on Earth, so they are not only beautiful, or sometimes impressive, or scary, but also crucial by bringing rain and feeding plants and trees. …

Introducing a vaccine against COVID-19, which literally makes our own cells produce the antigen (something that triggers an immune response, in this case, the spike protein), already sounded like a terrible idea. Now more and more data pours out, which confirms that this was really a bad idea.

How Do The Current COVID Vaccines Work?

I will describe it briefly, if you want to read more about this, you can read it here. The vaccine introduces an mRNA sequence in your body cells. Because of this, your own cells start to produce a spike protein and express this spike protein outside your own cells, but spike proteins…


As a gross generalization, we can say everything in nature has a purpose and is made as efficiently as possible. As humans, we have managed to withdraw ourselves for a significant part from the influences of nature. Our brains provide us with intelligent solutions which made us independent. We can make a shelter, make fire, make sick people healthy again, and provide our own food. This has a lot of advantages and has placed us more or less outside the evolutionary pressure. Survive of the fittest has turned into survival of the smartest. …


Your idea about science may be completely wrong. If you think that science is about hard facts, irrefutable theories, and strong statements without room for doubt, this article will explain the scientific method and show you that you might have to readjust your ideas.

The Scientific Method

The scientific method is a cyclical process through which information is continually revised. Science is not a static entity, and theories that were accepted for a long time can be replaced with newer and better ideas. The scientific method is an empirical method of acquiring knowledge that has shaped the development of science since the 17th…


You Will Never Guess, It Even Involves Risotto

The life of the Professor revolved around a single idea: Resistance. His grandfather, who had fought against the fascists in Italy, taught him the song and he taught us.

this is a quote from Money Heist. (La Casa De Papel)

I watched the series (I am slow with catching up with series…), and this song, `Bella Ciao´ caught my attention. It kept playing in my head. I was thinking about the origin and was thinking about Spain and the Spanish Civil War (1936–1939, Nationalists (Conservatives) vs. Anarchist (Communists)). I already made up my mind that it could be a song…


In the late 60´s Calhoun performed an experiment in which four pairs of mice were kept in a nine-square-foot enclosure. The mice lived in a plague-free environment, with an abundance of comforts, a lack of predation, and an unlimited supply of consumables. This population grew to 2200, they created social order, but they also ceased to mate. Within two years, the entire society went extinct. He performed this research to test his hypothesis: overpopulation spawns a breakdown in social functions, and that, in turn, inevitably leads to extinction.

Calhoun’s theory has raised concern that the social breakdown could ultimately serve…


We are more than a year in the COVID crisis. A crisis caused by the reaction to a virus that has an infection fatality rate of 0.23%. (Ioannidis , 2021) There are so many aspects of this man-made crisis that deserve deep analysis, and a lot has already been written about this, but there is one number that is overlooked and used in the wrong way, and it is in plain sight.

Epidemiologic Numbers

To describe a disease in epidemiology, doctors use different numbers. One of those is the already mentioned IFR, or infection fatality rate; this is the number of people…
