It is never right to play ragtime fast. -- Scott Joplin When I'm dead twenty-five years, people are going to begin to recognize me. -- Scott Joplin Let me see you do the 'rag time dance'... Turn left and do the 'Cake walk prance'... Turn the other way and do the 'Slow drag'... Now take your lady to the world's fair (...)

When the stress response is ongoing other minerals can actually build up in the body, such as potassium, sodium and phosphorous. This is due to a change in intestinal absorption (since digestion takes a back seat when we are in fight-or-flight mode) and re-absorption by the kidneys of these elements.
Short-term memory impairment and concentration problems can change from day to day, and/or from moment to moment. All of the above combinations and variations are common. Anxiety causes the body to produce the stress response (also known as the fight or flight response). The stress response stresses the body, which can have an adverse effect on brain functioning. Research has found that stress can impair the short-term learning and concentration areas of the brain. This is why when stress elevates, many people experience short-term memory and concentration problems.
