Did you ever hear the expression “Use it or lose it?”
The human brain has billions of connecting neurons and trillions of connections between them. Neurons are brain cells.
We are born with 100 billion of them and as time passes in childhood, unused neurons die off. We loose them.
In our very beginnings, neurons are designed for us to develop emotional connections to parents, and thus having developed these strong, positive attachments, be able to trust them to provide the very best for us.
If those early connections with parents are not developed well, then the neurons designed for that connection are unused, so they die off.
Does that leave you hopeless – unable to connect intimately with someone? ABSOLUTELY NOT!
