The human mind, like any other creature that uses its intelligence to survive, has developed certain qualities that make it more vulnerable to fear. We are often fearful of people we know who aren't actually threatening us, but we're scared of strangers - or even imaginary people - who might do us harm.
As a species, human beings have a tendency to be suspicious of other members of the species, and they have developed different ways of coping with that suspicion. This has resulted in some strange situations that we find ourselves in as a result. We have very strong instincts to protect our own lives, and we often find ourselves trying to fight off intruders or protect friends and family.
Because we've evolved in such a way that we're often suspicious of others, the human race has a tendency to be self-protective. Our ancestors, who lived in tribes, had to use whatever means they could to protect themselves from predators. One of those means was to become as invisible as possible to potential enemies. The other means was to turn their heads away from an intruder's eyes.
The fact is, even if we haven't evolved to face an actual physical threat, we still have a need to be able to protect ourselves. When we can't do that, we often turn to our mental faculties to try to protect us, and this can be rather unnerving.
To understand why human beings are so insecure, you have to take a look at the structure of the human brain. The human brain is one of the most complex creations in the world, and it takes special intelligence and a great deal of hard work to be as smart as we are. When something doesn't fit right, our brains tend to try to fix it, and in a way this leads to all kinds of problems.
Our human nature, which is part of our DNA, means that our brain tends to work in strange ways when something doesn't work properly. If we don't know why something is working, we can often get very frustrated with it and try to fix it. But the human brain is not a very good machine, and it can go wrong from time to time, which can lead to the wrong results.
For instance, when people are afraid of something, their brain will often try to correct them. If a person knows that something is wrong but doesn't know why, the brain will try to solve the problem by trying to solve it for them. This leads to their brain being very defensive.
Unfortunately, the result is that a lot of people who live with us because we are our friends often feel very defensive about it. But, instead of feeling too uncomfortable and insecure, we often feel as though we are being forced to fight back against something that doesn't really exist.
Of course, there is a reason why people are defensive about fear. When something that doesn't really exist attacks us, we all start to fight, and that means that we end up being even more defensive than we had been before. This is why they get so mad at us for being so worried, and that they often get defensive even more.
Why do we feel so defensive about fear? The answer lies in our brain, and it has something to do with our desire to protect ourselves. Because we want to stop someone else from attacking us, we become defensive and become angry. We then use these feelings as a means of controlling what happens to us.
If someone attacks us, we usually have a way of thinking that we can protect ourselves. If they attack us physically, we tend to think about what we can do to stop them. Or we might decide to run. We might start crying, or hurting ourselves so that we will feel better. But we usually don't think about why we are reacting the way we do.
That is what is so scary about human beings. They become defensive because they fear another person trying to hurt them. Instead of fighting back against someone who is trying to attack us, they fight back by becoming more defensive.
