Beginner in Game Development, Which Engine Should I Use? Comparison of Unity vs Unreal vs Godot (Focusing on Free Engines) Choosing a Game Engine: Know This First: 5 Key Q&A Q1. What is a Game Engine? Is it necessary to use one? A. Think of a game engine as a set of development tools that bundles essential functions required for making games, similar to a car engine. It includes features like rendering graphics on-screen ( Rendering ), physics effects for characters colliding with walls or jumping ( Physics Engine ), and playing background music or sound effects ( Audio System ). While it's possible to create a game from scratch without an engine, it requires an immense amount of time and effort, which is why most developers today use game engines, especially beginners! Q2. I want to start game development; are there any good free engines available? A. Yes,...
What actually happens in our body when using steroids?
Steroids: What Happens in Our Body When Building Muscle (Metaphor of the Cellular Kingdom)
Steroids: Key Points to Know - 5 Essential Q&A
Q1. What is the core principle of steroids in building muscle?
Steroid molecules bind to the 'Androgen Receptor (AR)' in muscle cells and enter the nucleus. The nucleus holds our genetic blueprint, where it stamps the command to 'produce more muscle protein, and do it faster.' This single command drastically increases the rate of muscle synthesis.
Q2. Do they only build muscle, or do they also prevent breakdown?
Yes, they do both simultaneously. While explosively increasing protein synthesis, they also weaken signals that break down muscle, like cortisol, a stress hormone. By increasing 'building' and decreasing 'destruction,' muscles inevitably grow at an abnormal rate.
Q3. What are the most serious health risks?
They can cause fatal damage to vital organs such as the heart, liver, and kidneys. The heart may enlarge and lose function, liver toxicity and kidney failure can occur, and they can completely disrupt our hormonal system, leading to infertility, testicular atrophy (in men), masculinization (in women), and severe mood swings or depression.
Q4. Do muscles built with steroids last a lifetime due to "muscle memory"?
There's an interesting hypothesis. Some of the 'myonuclei' increased by steroid use may remain even after stopping the drugs, allowing for faster muscle recovery when resuming exercise compared to others, known as the 'long-term memory' hypothesis. However, even if this is true, it cannot justify the health risks and sportsmanship issues.
Q5. Is it illegal to use them for athletic purposes?
Yes. The use and distribution of anabolic steroids for non-medical purposes are illegal or strictly regulated in most countries. Additionally, all sports organizations classify them as 'banned substances,' leading to severe penalties, including disqualification of athletes if caught.
Let's imagine our body as a vast kingdom. Within it are numerous cellular cities, each performing its own role to sustain the kingdom. Among them, the 'muscle' city is the most dynamic, responsible for the kingdom's strength and movement. One day, a powerful external envoy called 'steroids' arrives, and a huge storm begins to brew in the once-quiet kingdom. Through this adventurous narrative, let's follow how a single steroid pill creates drama within our cellular kingdom.
1. The Moment the Gate Opens: The First Encounter with Cells
A single pill or a single injection. With this small beginning, steroid molecules set off on a journey through the river of blood. The destination is clear: right in front of the muscle cell's gate. Above the walls flies the flag of 'AR (Androgen Receptor).' This AR acts like the kingdom's gatekeeper. The gatekeeper checks the unfamiliar guest, the steroid, and welcomes him, guiding him to the most sacred place in the kingdom, the 'cell nucleus.'
The cell nucleus is a vast library containing all the information of the kingdom. The genetic blueprint of our body is stored here. The gatekeeper AR approaches the shelves with the steroid and retrieves a scroll (DNA) that reads "Increase muscle protein synthesis" and "Amplify growth signals." Without hesitation, he stamps it with 'activation.' From this moment on, all workshops (ribosomes) in the kingdom begin to receive an overwhelming number of orders.
2. Awakening of the Workshop: Muscle Synthesis and Myonuclei Expansion
The stamped orders are delivered to the workshop that builds muscles, the ribosomes. The machines in the workshop, receiving far more orders than usual, start working frantically. Proteins, actin and myosin, which make up muscles, are produced non-stop and begin to pile up in the warehouse.
But this is not enough. To expand the production line, more hands are needed. At this moment, a type of stem cell called 'satellite cells', waiting around the muscle cells, is called upon. The satellite cells rush in and merge with existing muscle cells, donating their nuclei, or 'myonuclei'. This is akin to a new librarian coming in to speed up the copying process in the library. The more myonuclei there are, the more commands can be issued to produce muscle proteins, and the faster they can be given. As a result, muscle fibers are reborn as much larger, thicker, and stronger structures than before.
Episode: The Risky Experience of Aspiring Bodybuilder Kim Cheolsu
Aspiring bodybuilder Kim Cheolsu succumbed to the temptation of steroids for faster growth. For the first few weeks, he felt incredibly satisfied as his muscles grew remarkably. However, it wasn't long before abnormal signals began to appear in his body. He developed severe acne on his face and back, and his blood pressure soared, causing constant headaches. "My body in the mirror grew, but my real body was screaming." He only realized the high cost of rapid growth after quitting the drugs.
However, building muscle is not just about making it; it's also important to prevent it from breaking down.
3. Changes Outside the Kingdom: Ripple Effects Throughout the Body
Such changes do not occur only within the muscle cell kingdom. Outside the kingdom, much larger ripple effects begin to take place. The increase in red blood cells in the blood enhances oxygen transport, and the body retains more water, leading to rapid weight gain.
But this is just the beginning. The liver becomes overworked and exhausted, and the balance of cholesterol in the blood (good HDL decreases, bad LDL increases) begins to break down, causing blood pressure to rise. The heart beats harder, but if the plumbing (blood vessels) cannot handle it, it sends signals of overheating. Moreover, the highest regulatory organ of our hormones (HPG axis) senses the continuous influx of powerful hormones from outside and initiates a 'silent rebellion,' deciding it no longer needs to produce hormones. The result can manifest as serious aftereffects such as testicular atrophy, infertility, and depression.
Episode: Lee Gangmin's Suffering After Stopping the Drugs
Lee Gangmin, who once used steroids, experienced even greater pain after quitting the drugs. His body could no longer produce male hormones, leading to chronic fatigue, severe depression, and muscle loss. "I felt like I lost all my health and vitality in exchange for gaining muscle." He had to endure several months of difficult times receiving treatment to restore his damaged hormonal balance.
4. The End of the Adventure and the Choice
The adventure into the cellular kingdom has concluded, and now a choice remains. Steroids certainly force open the door to muscle growth scientifically, but alongside that path stand numerous warning signs regarding health, hormones, cardiovascular issues, and mental health. While the barbell may feel lighter in the training room, invisible costs accumulate in the ledger of our lives. As the desire for 'heavier, bigger' intensifies, we must remember the most basic and safest solutions: consistent training, adequate nutrition and sleep, and time. The quick path often leads us to cross rivers from which we cannot return.
Steroids: Remember This (FAQ)
Q. Please summarize the most serious health risks.
The major risks include cardiovascular (decreased heart function, increased blood pressure), liver/kidney damage, and hormonal system collapse (infertility, sexual dysfunction, etc.). Mentally, one may experience severe emotional swings or depression.
Q. How exactly does the hormonal system break down?
When powerful male hormones (steroids) continuously enter from outside, our brain concludes, "We no longer need to produce hormones," and stops the production factory. This leads to reduced reproductive function, and recovery can take a very long time or result in permanent damage even after stopping the drugs.
Q. What about the legal and regulatory aspects?
Non-medical use and distribution without a doctor's prescription are regulated as illegal in most countries. Additionally, all official sports competitions designate them as 'always banned substances,' leading to strict penalties such as disqualification of athletes if detected.
