Maybe they are stooped 🙂. Dont you lose some height the older you get? I think the elastic cartilage in your knees in your spine etc disintegrate over time...

That's because over time their spines compressed and they became short... does not mean they were always short (though the definitions of tall and short have changed a bit over the past 50 years... my grandfather was considered a "giant" and he was only 6')
 

If you look at mammal in general, then larger could mean longer life span due to less heart beat per minute. (Don?t have to work as hard to keep warm)

Whales Elephants, Rhinos, hippopotamus, etc... live much longer than mice.

Same thing could be said between primates. The larger Gorillas, Baboons, etc... life span is relatively longer than the smaller marmosets, monkeys.

It is difficultto gauge human life span to sizes, because you have extreme in diet & living condition.

It is also hard to say which will have longer life expectancy, midgets & giants life span is about the same length. Midget body worn out quicker & giant tend to have heart failure due to the body size.

But if you must compare then size does matter. People in developed countries tend to have better food & medical therefore our size & life expectancy is relatively longer than the malnutritious (undersize) people of third world countries.
 
Interesting stats here.

Short people seem more likely to vote and less likely to give a reason why they voted that way.
Tall people seem less likely to vote for themselves but certainly are more outspoken about it. 😉

It used to be that 5'7" was the midline of heighth in the world for men and 5'3" the midline for women, but anyone have current statistics on it?
 
But during my whole life I get the upperhand, becuase I am taller, and you are shorter. And when I die, and you are alive, you can be happy, but you will still be short.

The bigger they are, the harder they fall.
Ther shorter they are, the further they fly 😛
 
Just a guess but I think tall people are more likely to have a lower BMI therefore less likely to have heart disease or diabetes.

5'7" was the average North American male height for the 70~80s, but I think that it is slightly higher now due to the chemicals/steroids in food.

Yep! My parents shrunk. My dad was a tall man, but now he looks short to me because I am taller than he. But he was about 6' 1" tall when he was younger. Same with my mum.

"Just a guess but I think tall people are more likely to have a lower BMI therefore less likely to have heart disease or diabetes."

That's what I think too. I mean, tall people carrying heavy weight isn't very common, whereas it is common amongst short people. But then again, there aren't very many tall people on this earth. So maybe it's a bad comparison.

If everyone has the same general internal layout then I can see the argument that short people make their hearts work harder because of the restricted vessel diameter. Anyone remember what r^4 power represents when figuring fluid dynamic pressures? Seems like twice the radius is 1/16 the pressure. Its possible that short people won't necessarily have smaller diameter blood vessels, too.

On the other hand in the animal world the large beasts live much longer than the small ones.


this assumes that tall and short individuals have the same amount of blood. this is not the case.
 
For those interested last I heard (1999) I believe the average height for a male of 18 years in North america was 177cm. For a female the average height in north america was 165cm again at 18 years old. This corresponds to about 5'9.5" for males and about 5'5" for females.

As far as the question of lifespan, I seem to recall reading somewhere that shorter people live on average a bit longer, but other factors such as genetics, diet, and environmental factors play a much larger role. Therefore unless you are more than a foot removed from the average I would not be too worried about it. On the other hand those on the extremes do not live as long. (midgets and giants if you will).

If the blood is in proportion than the larger animal/person does less work. As the lifeform grows in size the relative density of the blood lessens, even if the blood is identical in its constuents.

The latest office debate. Its simple, do short or tall people live longer.

Short people supposedly have smaller bloodflow pipes, therefore it increases their blood pressure.
Tall people supposedly have uphill battle against gravity, therefore the load on the heart increases.

So which is it, and why? 😉

Battle against gravity? 6' at 135lb...I may have issues, but fighting gravity definitely isn't one of them..😛
