The computer brain

In the 1930s a neurosurgeon named Wilder Graves Penfield discovered, through electrical stimulation of certain areas of the brain, that people can remember some past events and how they made them feel. Penfield concluded that the brain works like a computer with memory banks; it records and stores specific things we see or hear and those memories and feelings are often replayed and relived as vividly as when they first occurred.

What do you feed your mind on?

The memories and emotions stored on the brain can be triggered back to life by a statement or deed, and can affect the rest of our day negatively or positively. Thus a bad history and unpleasant experiences often influence an individual's attitude towards life. The brains of pessimistic people are full of negative data from bad past experiences. 

But with this knowledge you can change that. As a child you probably had no control over what entered your brain, and you are still struggling to cleanse it of all the negative vibes projected onto it. But as an adult, you have control over what is stored on your mind. If you surround yourself with people who are worriers, or who can't speak three words without cussing, your brain will save sad and dirty vibes and before you know it your speech will be depressing and your disposition sour. If your idea of weekend entertainment is watching pornographic movies don't be surprised when you end up raping  your maid. 

Paul the apostle said we can shield the mind from corruption by thinking only on things that are true, honest, just, pure, lovely and of good report; things that are worthy of virtue and praise. Feeding on such uplifting things by choosing carefully who we interact with daily, what we see, read and generally participate in, will enrich the bank memory of our brain so much that it will store and replay memories and feelings as will only orchestrate success, beauty and happiness in our lifestyles and relationships.
