I believe every human has a finite number of heartbeats. I don't intend to waste any of mine. Neil Armstrong
And you know, Neil Armstrong never said this. Then, should we believe this concept? Is there any backing for this quote that research can prove. Of course yes. According to a new research published by a team of Danish researchers in the journal BMJ Heart, there is quite an evidence to prove the strong positive correlation between resting heart rate (RHR) and mortality. Has the time come for you to keep track of your pulse until you have used all your allocated pulse? Should you immediately stop exercising in order to calm down your pulse?
How was the research down and what is the inference?
Scientists said that this is a 16-year work conducted on 2798 men. Roughly 1082 deaths occurred during the course of the research for different reasons. With the available data from the rest two-thirds men, scientists found that- RHR was inversely proportional to physical fitness.
- Increasing RHR was directly proportional to mortality.
- Compared to men with RHR less than 50, men with RHR more than 90 have a higher risk of mortality.
- The risk of mortality increased by 16% (10–22) for every addition of 10 beats per minute (bpm)
- Elevated resting heart rate is an important risk factor for mortality. The risk is independent of physical fitness, leisure-time physical activity and other major cardiovascular risk factors.
You can check out this website to get an idea about the RHR of different animals.
Humans have an average RHR of 60 to 70 bpm and can roughly live for 70 years. This accounts for 2 billion beats.
Chickens have the highest RHR - 275 beats per minute and can live for 15 years. The total beats in one life account for 2 billion.
A whale has 20 bpm of RHR and lives for slightly longer than us. So, a Whale gets only 1 billion beats.
To conclude, the rule isn't hard and fast one, showing only a few million of difference between the organisms.
