Do you personally believe that your personality, intelligence, or health, are a matter of destiny?
If you do, then you believe in fatalism!
You believe that you cannot do anything to improve your own life, which is entirely wrong.
This is your excuse to do nothing to improve your present life circumstances.
Today we know: humans are not determined by genes but determine by the environment. We can influence and change our genes respond to the environment.
Epigenetics is very clear: Genes can change, in both ways.
If you care about your life and pay attention to your environment, food, social life, stress, and exercise, you can better change your present life.
If you do not care, unhealthy life is your reality.
Many people, wrongly, believe that they cannot change being short-tempered. “It’s my nature, or it’s in my genes,” is their explanation.
This is not true, and neuroscience knows why it is not valid.
Neuroplasticity has discovered that the brain can and does change continuously throughout an individual’s life.
With its 100 billion neurons (brain cells), communicating with each other carrying information, the brain is the most complicated “machine “on the whole planet.
Every time you’ve learned something new, or have new thoughts, or you repeat an idea, the connection between neurons grows.
Let say you have to learn a new language. Whenever you use a new language, you are growing your brain connection for that language. After a while, you’re almost fluent in this language. Neuron’s connections are strong and stable because you use this new language very often.
Imagine now, using the same strategy: you have a short temper, hurting other people with sharp, insulting, or sarcastic words. Repeating this behaviour, like repeating a new language, you are making neurons connection stronger because you have a terrible temper, repeating the same behaviour all the time.
The simple solution to change your bad temper is to forget it. Next time, when angry, do not use your bad language.
When you stop a habitual bad temper, the connection between neurons will shrivel up and disappear. You will forget to be nasty because your neuron’s connection for bad temper is gone.
Similarly, if you stop using a new language, you will forget it.
The neurons associated with a new language, or bad temper, will be literally “deleted” from your memory.
