Extroverts Handle Cold Better

20 people isn't considered a statistical viable population, but maybe it will open the door to more research with larger study groups.

Good thinking.

Larger people handle cold better too.

Wrong. Larger people have a larger surface area, and therefore lose more heat through convection than smaller people.

Think again. Volume increases as the cube whereas surface area increases as the square.

Whales are really big... they don't lose heat fast.

Lots of surface area.

 

Insulation helps. Big people have more "insulation" than small people.

yeah, and narwhals have built-in monopoints

[G-spotter]

ooops, sorry, better make that "gnarwhals" for the extremeness of it all. sick brah! nice horn you're driving!

I did not state the function of Surface Area v. Volume. Larger people have larger surface area. What is there to think again about?

 

Additionally, because larger people have a larger volume, as you correctly stated, they have higher energy requirements and need more food to maintain homeostasis.

They lose more heat, but they have a lot of heat to lose. Indeed more food is required.

[G-spotter]

volume generates heat through metabolism and surface area loses heat; that's why wooly mammoths were so big

[G-spotter]

also, wooly mammoths were extroverts. this proves the original point.

[ClimbingPanther]

CBS is right. Larger people have more heat stored inside their bodies proportionate to the amount of surface area, therefore what they lose due to their increased surface area is less significant.

 

Try telling your oven that the 40 lb. Thanksgiving turkey you bought has more surface area than chicken nuggets.

[Choada_Boy]

1)An entire chicken has more surface area than a single chicken nugget.

 

2)It takes less energy to cook a single chicken nugget than it takes to cook an entire chicken. Therefore it takes less energy to keep a chicken nugget warm while it climbs in the winter than it would for an entire chicken.

 

3) Woolly mammoth tusks turned inward, indicating that woolly mammoths were in fact introverts.

 

Question: Why are small dogs preferred over large dogs on dog sled teams?

[G-spotter]

small dogs are preferred over large dogs because they generate less dogshit. frozen dogshit on sled runners drastically reduces the speed of a sled.

Dru knows this from experience. He knows his shit.

[ClimbingPanther]

There's a lot of factors at work here, and how fast a person cools down depends not only on their s.a.:mass ratio [fat-advantage], but as you say on their metabolic capacity to generate heat to replace what's lost. I don't know the difference between fat & skinny people's ability to generate heat, but if it's the same regardless of size, then things even out. If fat people can generate proportionately more heat, then they will definitely outlast a skinny person no matter what. Unless they're gored by an introverted mammoth.

[G-spotter]

Muscle generates heat. Fat retains heat but does not generate it.

[ClimbingPanther]

Question: Why are small dogs preferred over large dogs on dog sled teams?

 

Because they don't overheat while running since they lose a greater percentage of their body heat

My point.

[ClimbingPanther]

not exactly... they're comparing equal volumes

 

quote from said article:

"A low surface area to volume ratio helps to conserve heat"

 

fat people have a lower ratio.

my point.

 

 

http://en.wikipedia.org/wiki/Bergmann%27s_Rule

also my point.

But what does any of this have to do with extroversion?

[G-spotter]

Small, fat people like you are probably introverts. That's what it has to do.

Ha, ha, ha, ha. Look who's talking!
