It'd be nice if the submitters started reading their own articles.

The lifespan of every mammal is one billion heartbeats, more or less

FTFA: animals from shrews to blue whales have lifespans with just about equal number of heartbeats - about one and a half billion, if you simply must be precise.

It's an interesting article though.

If your heart beats 60 x a minute, 1,000,000 is only 32 years. 1.5 = 48 years.

Humans aren't mammals?

Your math is off. You used 1 million, not 1 billion, and still weren't correct.

If your heart beats 60x a minute, and there are 1440 minutes in a day, and 365 days in a year, then 1 billion beats gives you a life-span of 1902 years.

Ummmm..

1,000,000,000 beats/60 beats per minute ~ 16,666,666 minutes
16,666,666 minutes /60 minutes per hour ~ 277,777 hours
277,777 hours/24 hours per day ~ 11,574 days
11,574 days/365 days per year ~ 31.8 years

So it looks like EnviroDude was right after all.

/and doesn't diminish the interesting result one bit

1 billion seconds is approximately 32 years. My apologies to all for only writing 1,000,000 in the original post.

Your pulse rate goes down dramatically while you're asleep, and most people are in that state for half or 1/3rd of the day.

Assuming a third, that's about 71 years... which is about right for history.

I've always wondered if the lowered resting heart rate in a healthy individual is responsible for an equivalent reduction in absolute number of beats as are added by the exercise. I also wonder if I could have phrased that sentence better.

I don't think you need to make an adjustment for sleeping. Animals sleep too. The average life span of man in the wild is much lower than 70 years. It is thanks to civilization and medicine that we live as long as we do. Take a look at life spans in history.

I first saw this calculating lifespans by heartbeats in an old Asimov F & SF article. Boy I miss those monthly science articles.

Y'know, that makes a lot of sense. It may be that we fat farkers, with a faster at rest heart rate burn through our billion beats much quicker and when you exercise then you lower your resting heart rate and spread them out much more.

Interesting. I have become SPAWN.

Actually, more so. You want to have a healthy heart, start distance running.

Your heart beats fast now, so it can beat much more slowly later. The one activity you do more than anything else in your life is sleep. That's where you extend your life (ala slowed heartrate).

RexTalionis: Your pulse rate goes down dramatically while you're asleep, and most people are in that state for half or 1/3rd of the day.


Newborns have a much higher heart rate, around 140-160. It settles down pretty quickly; my point is this is not meant to be exact. It's a statistically significant correlation between heart rate and average mammal lifespan. There are significant deviations and humans are one of them.

It's more insightful for biologists analyzing the potential lifespans of various species than anything. For example, it's unlikely a rat can live as long as an average human regardless of any sort of genetic modification; the lifespan is limited by the chemistry of metabolism and physics of pumping blood through a very constricted circulatory system. The heart eventually just craps out.

2011-11-29 02:38:52 PM  
hmm, I knew this 20 years ago from some BBC nature programme. All mammals except humans have roughly the same number of heart beats. Explains why elephants live longer than horses live longer than cats live longer than mice.

Oh, oh, oh, oh.
Yeah sure maybe I'm on the edge
But I love you baby and like I said
I'm here to tell you

Every hour, every day.

Every heartbeat bears your name
Loud and clear they stake my claim
Ask anyone and they'll tell you it's true
Every heartbeat belongs to you.

Every heartbeat bears your name (every)
Loud and clear they stake my claim, yeah
My red blood runs true blue
And every heartbeat belongs to you.

And did he explain to you that his heart beats fast during his runs so that it can beat extra slow when he sleeps? ....and the fact that sleeping is the one activity we do more than anything else in our lives, so anything that improves our health while sleeping elongates our lifespan?

My husband's theory was we all have only so many steps in us. Kind of along the lines of the heartbeat thing, but I asked him why regular runners tend to live longer then couch potatoes. This makes sense (because the runner would have a lower resting heartrate).

The idea is that an avid runner is going to have a slower resting heart rate, and even the running heart rate is going to be slower as you get better at running. Over a long enough period, being a runner wins.

Well, to be fair, the 1.5 billion beats thing seems to be more of a "natural life-span" thing. The environmental conditions humans have recently built around themselves are a bit of an aberration in the larger sense, thus the sharp deviation from the expected three decades or so in the first world.

Actually quite a few runners and athletes die young. I've known several.

When you can lie down, lie down. When you can sit, sit. Don't run, just walk.

If you run for 2 hours, you have run for two hours. Sure, you may have a few extra years in you when you're too old to enjoy it due to failing taste buds and other nerve endings.

If I don't run for two hours, I have more time to cook bacon and eat bacon. While I still have functioning nerve endings and can enjoy it.

Then I can lie down the second hour cause eating a sack of bacon makes me tired.

The only person in the thread to get it right.

If anyone felt like reading the source for the article, you'd see it says:

Human beings used to fit into this pattern, but now that we have learned to drink safe water, wash and bathe and create medicines, we last longer than our size would predict.

The 32 years' average life expectancy isn't even that far off, if you look at countries like Mozambique or Swaziland (both under 40). Granted, much of it is due to the rampant AIDS epidemic.

"Of course time exists -" As a concept in your head. If you weren't there to cling to it, were would "time" be? Wherever your mind isn't, I suppose.

"But physics teaches us something remarkable: every event in the past and future is implicit" - only when you impose your conceptual fantasy into the frame, Mr. Cat.

There are collections of his F&SF science articles out there. I own several. Check around online. Decent, largish used book stores will usually have half a farkin' shelf of them (I don't think many people buy them). Want 'em all and I think you're talking about 20 or so volumes, but they're usually very cheap. AFAIK (though I haven't checked in a while) they've not been reprinted and there are no e-book versions (not even pirated ones), though a lot of the individual articles are floating around online.

His guides to The Bible (yes, seriously) and Shakespeare-are also fabulous. IDK about the Shakespeare one, but his guide to The Bible was reprinted a few years ago, so nice, new(er), cheap hardcovers are fairly plentiful.

Asimov's Guide to Science is good but comically dated. Digging trenches with nuclear bombs indeed :)

Don't have his Gilbert and Sullivan book, but it's on my to-buy list.

/ Think his fiction blows goats; it's often like reading crap kids in an advanced high school fiction-writing class might write, in terms of the prose and characters especially.
// His non-fic is goddamn terrific though, and fortunately for us there's a lot of it.
