The correct answer is letter A
Sinoatrial node (SA) or pacemaker or sino-atrial node: special region of the heart, which controls the heart rate. It is located near the junction between the right atrium and the superior vena cava and consists of a cluster of specialized muscle cells. The rhythmic frequency of these muscle fibers is approximately 72 contractions per minute, while the atrial muscle contracts about 60 times per minute and the ventricular muscle, about 20 times per minute. Due to the fact that the sinoatrial node has a faster rhythmic frequency in relation to the other parts of the heart, the impulses originating from it spread to the atria and ventricles, stimulating these areas so quickly, so that the rhythm of the SA node becomes the rhythm of the whole heart; that's why it's called a pacemaker.
Answer
Hi,
Delayed gratification applies in retirement in that it can allow a person to qualify for a higher social security payout.
Explanation
Delay of gratification is when a person resists the feeling of taking an immediate available reward while hoping to obtain a more-valued reward in the future. In this stand, one could argue that delayed gratification would make sense in retirement because the social security payout will last longer since it won’t be tapped until later. However, life is short thus another person won’t delay his retirement so long to get the time to enjoy it.
Hope this Helps!
