What specific evidence would you need in order to determine that while watching something exciting your pulse rate increases?

To determine that your pulse rate increases while watching something exciting, you could use the following evidence:

- Take your pulse before and after watching something exciting. This will give you a baseline measurement to compare to.

- Use a heart rate monitor to track your pulse. This will provide you with a continuous measurement of your pulse rate, so you can see how it changes over time.

- Pay attention to how you feel. Do you feel your heart beating faster? Do you feel more flushed or sweaty? These could all be signs that your pulse rate has increased.

- Ask someone else to take your pulse. This can help you to get an objective measurement of your pulse rate.

- Compare your pulse rate to the average resting heart rate. The average resting heart rate for adults is between 60 and 100 beats per minute. If your pulse rate is higher than this, it could be a sign that your pulse rate has increased.
