Since the solar year consists of 525,948 minutes and 48 seconds, a quick calculation at the rate of 80 BPM gives us a ballpark figure of 42,075,904 beats per year, give or take a couple mill. A reasonable estimate for the number of heartbeats in a lifetime is about three billion.\n\nhttp://www.straightdope.com/classics/a1_088a.html

Textbook answer is 70.\nthough 60 to 100 is classified as normal for resting.\n\nif you are fit, like the so called olympic cylcer, you resting heart rate can (very rarely) go as low as 30.\n\nyour maximun heart rate veries with age, but most people hardly reach it.\nTake 220 and subtract your age, that's your aproximate maximun heart rate\n\nhowever, if you have a heart probelm or are taking medication, your heart rate can change: eg\nbeat blockers slow your heart

a normal pulse rate is 60-100. You may need a physical if your HR and BP are up and has never done this before. You may just be out of shape or pushing yourself more, but it may be something more serious like heart rhythm prob or defects, anemia, etc.

It is different for everyone. Anything less than 60 beats per minute is regarded as bradycardia. Good gas exchange doesn't usually occur at under 60 beats per minute, or over 100 beats per minute. The high end is 100 beats per minute. Anything above that is considered tachycardia for which a medical intervention is required.\n\nNow that being said, when you work out, your heart rate can exceed 100 beats per minute. That is why it is important check your heart rate regularly during exercise to make sure you haven't exceeded the maximum heart rate and also cool down properly when exercise is completed. When you heart rate is high and you stop activity abruptly you can cause yourself to have a heart attack.  When working out it is best to maintain your target heart rate. Below is some helpful information about heart rate.\n\nHere is the formula for the target heart rate. It is different for every age:\n\nhttp://www.stevenscreek.com/goodies/hr.shtml\n\nMiller formula for maximum heart rate:\n\n217-(0.85 x age)= maximum heart rate

I know much about the heart. It's one of the most important organs in your body. (probably the most important if you want to stay alive). It is a very complicated system.\n\nYour question is too broad, I don't understand what you're trying to ask. Your question is more of an opinion one. If you have a particular question, I'd would be glad to answer.

Normal resting heart rate for an adult is 60-100 beats per minute.  It can be less if you are a trained athlete and more if you are overweight.  This is a general guideline.

Not unless your on digoxin. The average heart rate is 72 beats per minute. Now not everyone will be 72bpm but at \n37 your heart rate should be a little closer to normal. See a doctor and see what he says.

the human heart is capable of very low heart rates to very high rates. physiologically each heart beat is completed in 0.8seconds, thus the number of heart beat per minute is 60 divided by 0.8= 75 beats per minute. the physiological phenomenon are always given a range value rather than a precise number since every individual is different. hence heart rate ranges from 60-90 beats per minute which can also be as low as 40 for athletes due to vagal tone.

that could be roughly true\nit depends on what is your heart rate (which as a matter of fact varies a lot through the day, and at different ages it varies too) and how long you live\nFor example babies have heart rates of 120 to 140 beats per minute while adult range from 60 to 100 \n\nIn the hypothetical case that the heart rate was kept constant through your entire life lets say at 60 (To take the lower end) and that you would live exactly 70 years that would be \n\n60 beats per minute times 60 minutes = 3600 in an hour\n3600 beats in an hour times 24 hours in a day = 86400 beats in a day\n86400 beats in a day times 365 days in a year (If all years had exactly 365 days but that is not true either)= 31536000 beats in a year\n\nand finally 31536000 beats in a year times 70 = 2207520000 (2.2 billion).\n\nSO your teacher is right if we take all these considerations but in life sciences the rule is that nothing is kept always constant
