Your immune system gives you the feeling of hope, protection, and safety. But what if I tell you, as many things are, your immune system is both a blessing and a curse? Because cells, as you can see, don’t have brains. They cannot think. If they feel that there is an invasion from their programming, then they attack.
What stops them from thinking that your cells are invaders? Well, nothing, except programming. But if that fails, too bad, now the city is under attack by itself! The immune system will now attack your own body, which may either kill or disable the area. The steps of defeating an invasion are followed by your body, since now it thinks you are the enemy.
The symptoms can differ depending on the area of your body that it is happening on. For example, an autoimmune disease in your brain could mean fatigue, memory loss, and your logic may not be clear.
