Doc, please don't say that this article explains everything.
It does not !! I don't see even a bit of definite evidence here.
The whole thing is just a bunch of stupid imaginations as if some idiot saying,
“God has given each of us just so many heartbeats,...”
If this is true, I should have died a long time ago !!!
I should have run out of my quota of my heartbeats. Why am I still alive now??
1. Then why did you (or I, too) insert pacemakers in people with severe bradycardia?
Were you (or I) trying to kill the patient?
2. If we are to have only so many heartbeats in our lifetime, why do you recommend people to exercise??
When you say to your patient to exercise, did you mean that they should kill themselves sooner?
3. Look at the people on the treadmills in the exercise room. Are they suicidal?
4. Should you, as a cardiologist, keep your patients in bed so that they can live longer?
5. Should you have prescribed "Inderal or any strong beta-blockers" to every patient of yours
to increase their longevity?
Here's a "funny or sarcastic" example of what you have been telling your patient in your office.
"John, do some exercise, such as brisk walking 30 minutes at least twice a week,
so that you can shorten your life span. 그러면 빨리 되질테니까. 알겠지?"
Then, you charged him for his office visit for your wonderful medical advice !!
Doc, you had put up an article like this before on our website as I remember.
Do you tell your patient, "Don't bother to get up in the morning. Just stay in bed to keep your heart rate slow."
"If you get up and move around, you will be running out of the God-given numbers of the heart rate."
You also would have said, "Please don't engage in the sex. It will kill you sooner than you think."
Please quit doing this nonsense.
I very much like to see your "wise" answers to my "stupid" questions.

You got it all wrong, WM.
Regular aerobic exercise brings down the resting heart rate so that
the tachycardia during exercise is nothing when you count the heart rate
per day, per month and per year because a physically conditioned person like yourself
through regular exercise has brought down the resting heart rate to low 60's, 50's even 40's
compared with a non-conditioned person's resting heart rate between 70 and 100.
The pacemaker requiring bradyarrhythmia such as the case of complete heart block or
sick sinus node syndrome
is a disease state, which certainly is not what we are talking about.
What we are talking about is the normal cardiac physiology of a normal person with a normal heart.
The only way a normal person brings down his resting heart rate is by doing aerobic exercise regularly.
We haven't done a longevity study by giving beta-blockers to normal people.
But we did tons of studies by giving beta-blockers to coronary heart disease patients and heart failure patients
by doing double-blind studies, all of which indeed show longer survival.
So what this article is saying is that if a normal person maintains a lower resting heart rate by exercise,
that person's natural longevity may be prolonged as observed in the animal kingdom.

The basic defect in this theory is that "Regular aerobic exercise brings down the resting heart rate".
It may sound like "true and real" by a foolish common sense.
It actually may not. Rather, it seems to me that, more likely, everyone has his own resting heart rate
which he was born with, no matter how hard or frequently one puts himself into aerobic exercises.
My resting heart rate has never been less than 72/min even in complete rest even after an exhausting climb.
I have been watching my own heart rate personally. My heart does not slow down by exercise.
Even in my old age, my rate never goes below 72.
I have a feeling that my heart rate will go down someday "only once for the last" in my death bed.
In the old days, people used to die at the age of 50-60s or even much earlier.
Now, we are dying at the average age of 70-80s or even 90s.
How do you explain this? Do you mean God gave less quota to the people of the last century?
Then, he decided to give more heartrate quota to modern men?
Kirk Douglas died yesterday at age of 102.
I am sure he had used up a lot of heartbeats more than anyone else in his exciting life.
How come he lived longer than a lot of sedentary people in our society?
The IRS of the U.S. has decided that I would die at the age of 98.
Does the IRS base on our longevity on the basis of God's quota?
They go by the statistics, not by the foolish God's quota.
It's amazing that you, as a cardiologist, believe in this stupid thing.
We die from diseases, accidents, or simply from the degenerative process in our body cells,
not by the number of total heartbeats given by God.
Do you know how many numbers of heartbeats your God gave to you?
You should know. How many was my quota?? How about the numbers in other friends of ours?
The heartbeat-quota should be all the same according to your belief.
The one who used up the numbers will die earlier than the other ?? ㅎ, ㅎ, ㅎ.

As you said, the resting heart rate variation may be one of many many factors
determining onc's longevity, It may well be one of minor insignificant determining factors.
Let's suppose you've been a sedentary couch potato instead of being true you,
a super physically active guy climbing all the mountains, what would be
your resting heart rate? I bet it will be significantly higher than it is now.
In early 1970's when Cardiologists introduced treadmill stress test into Cardiology practice,
I subjected some twelve interns and residents to the treadmill stress tests.
To the astonishment of theirs and mine, every one of them was found to be in deconditioned
state, with the average resting heart rate around 100/min which soared to the maximum HR
over 160/min with a few minutes of exertion. I told every one of them their conditioning level
is equal to trained men in 70's.
Part of the reason I said that was to motivate them to exercise.
After a few months, I brought them all back after confirming they did their homework.
To their pleasant surprise and mine their resting heart rates and fitness level were all back to
"near normal level" for their young ages.
This is what I'm talking about.
If one's resting HR is relatively high because of the genetic factor, that person has
all the more reasons to try to modify one's genetic predisposition by doing exercise
as you've done.
As a matter of fact, the principle of modern medical practice is just that.
First find out as much as you can what are good genes and bad genes you were born with.
Then secondly find out what you can do with the help of your doctors to modify your bad genes
to decrease the risk.

I think it will be "illegal" to practice under the idea of
“God has given each of us just so many heartbeats,...”
Please just think carefully about why I am saying it is illegal.
You may not get it right away but try to think that you apply this principle
"in reality" at each old patient of yours.
This is one of the oldest questions for most of the cardiologists
in their careers. I remember the lively informal debate on this question
between our mentor, Dr. Ellet Drake and Cardiology fellows in 1970
when I was in Cardiology fellowship training at Henry Ford Hospital.
What Dr. Herbert Levine is quoted in this article is not certainly the
original idea because my mentor, Dr. Drake said exactly the same in 1970.
Perhaps in my opinion every cardiologist one time or another in their careers
must've thought about the question.
This article addresses all the pertinent questions related to the resting heart rate.
