A very short lifetime - 1.

This is a very ironic question, I just took some weird "FUN" quiz on science about an hour ago, and one of the questions was how many times a day the average person's heart beat. Well, the heart beats approximately 100,000 times/day. Obviously this is a normalized value, people who work out and are in good shape will have different heart beats per day than a person who watches TV all day and eats chips.
as for lifetime heart beats, that's really hard to say since death could arrive tommorow or in 80 years. But daily, an average of 100,000 heart beats occur.
----Well, I can estimate a potential range for a person that lives until 75= 100,000 x 365 = 3.65 x 10^7 heart beats/year.
-----if the person lived until 75 = (3.65 x 10^7) x 75 =
=2.7375 x 10 ^9
This calculation is missing one thing: leap years, if the person lived until 75, they would have lived through 18.75 leap years, or approximately 19.
So, (100,000) x (19) = 1.9 x 10^6.
--------This is subtraced from the orginal calculation to give more "precise" estimate of heart beatsm although this subtraction reallly has no significant effect on the number, but just to not leave anything out...
(2.7375 x 10^9) - (1.9 x 10^6) =
= 2.7356 x 10^9 hearts beats in a lifetime
This isn't related to your question, but it's related to heart beat, it's just a very intersting fact I learned in a Biology of Cancer class last semester: An elephant lives 10 times longer than a mouse lives. However, the total lifetime heart beats of both the mouse and the elephant are almost exactly the same. I think that's a pretty cool fact, and I'm writing this at 4:18 am in the morning, so I get a pass if it's super geeky.

Assume a life span of 70 years, and a heart beat of 72 per minute. We get,
70 x 365 x 24 x 60 x 72 = 2649024000
So, take 2650 millions give or take a few.

Assuming 80 years, and also 80 heartbeats per minute, we get
80*365*24*60*80
which is approximately 3.36 billion heartbeats in a lifetime.
Gosh.

72 heartbeats per min for about 75 years equals to about 2,838,240,000 heartbeats on a lifetimes or 2.8 billion heartbeats

Your heart beats about 100000 times in one day and about 35 million times in a year

it's not of equal times

I have to say 300,000,000
