Answer 1

Answer:

yes it varies

Explanation:

Your pulse rate is the number of times your heart beats per minute. A normal resting heart rate should be 60–100 beats per minute, but it can vary from minute to minute. It can go up to 130–150 beats or higher per minute when you’re exercising – that’s normal because the body needs to pump more oxygen-rich blood around the body.

Answer 2

Answer:

Yes

Explanation:

Because the heart beat becomes lower and lower as we become aged. Your grandpa and grandma will have 50-60.But a new born baby will have 190-100.
