Blowing your thumb is a new method of reducing nervousness, at least discovered by me. This includes social nerves, action anxiety and other similar feelings causing discomforts.
When nervous, you realize that your heart beat becomes faster and uncontrollable. Slow your heart rate down by blowing on your thumb. Why?
The vagus nerve controls your heart rate, and you can calm it down by breathing steadily.
Keep blowing for a minute or two and observe the effect.
