Some “Basic” Cellular Biology
There are thousands upon thousands of receptors on each cell in our body. Each receptor is specific to one peptide, or protein. When we have feelings of anger, sadness, guilt, excitement, happiness or nervousness, each separate emotion releases its own flurry of neuropeptides. Those peptides surge through the body and connect with those receptors which change the structure of each cell as a whole. Where this gets interesting is when the cells actually divide. If a cell has been exposed to a certain peptide more than others, the new cell that is produced through its division will have more of the receptor that matches with that specific peptide. Likewise, the cell will also have less receptors for peptides that its mother/sister cell was not exposed to as often.
Thus if you have been bombarding your cells with peptides from a negative attitude, you are literally programming your cells to receive more of those peptides in the future. Even worse, you are lessening the number of receptors of positive-attitude peptides, making yourself inclined towards negativity.
This is why it takes more than a few days of positive thinking to make a significant impact on your long-term attitude patterns. Every cell in your body is replaced every 2 months. So if you have a history of negative thinking, depression, pessimism or perpetual frustration, plan on working on yourself for longer than a few days before you see more permanent results.
Start today. Start reshaping the biological structure of your cells and become inclined to happiness and optimism instead of whatever emotion your are physically addicted to right now.
