I see now that you totally did, judging by the looks of this room.

Hey, Animator, any chance we could resize Triangle Bob?

Itty Bitty Bob here has me thinking of a fun video idea.

What's the smallest size humans have ever been?

And how would it impact our world if humans were smaller?

Time to go on a journey through the land of human heights.

Welcome to Life Noggin First Station, Neanderthals.

These stubby folks stood about 5ft 5 inches tall and roamed around from 400,000 to 40,000 years ago.

Then we've got Homo floresiensis at just 3ft 6 inches tall.

When it comes to modern folks, the Pygmies of Central Africa stand at around 4ft 11 inches.

Compare that to the European guys 10,000 years ago who averaged 54ft 4 inches, a good 5 inches shorter than today.

Much taller than our Itty Bitty Bob here.

The average height for a little person or person of short stature is 4ft.

While the shortest person ever recorded was a Nepalese man named Chandra, measuring 1 foot 9 and a half inches.

An Iranian man named Afshin is the shortest person alive today, standing at 2ft 2 inches tall.

On one hand, poor nutrition can stunt growth, but

by limiting energy and protein necessary for cell development and by causing deficiencies in essential micronutrients required for various growth functions.

But another reason for some of these smaller heights are short stature disorders.

They're usually caused by genetic or hormonal factors that alter a person's development and bone growth.

Achondroplasia is one of the most common forms of a short stature disorder, accounting for 70% of cases.

This genetic mutation affects the growth of cartilage in the bones of a person's arms and legs, resulting in a larger head in proportion to the rest of the body and shorter limbs.

So how would life look if humans were smaller now?

Well, the average human is 56 for a male and 52 for a female.

Everyone being just a little smaller might have some impact.

Currently, you humans need about 25 to 30 calories per kilogram of body weight to maintain your weight.

But if human bodies were smaller and needed less food to fuel their diminutive daily activities, it would mean less food production is needed, and

that would lead to fewer carbon emissions.

The present food system is responsible for approximately 26% of worldwide greenhouse emissions, encompassing various stages like agriculture, packaging, and

Reducing the size of individuals might also result in decreased emissions, particularly in transport, which currently accounts for a significant 16% of total emissions.

Car manufacturers have already started producing lighter vehicles to enhance fuel efficiency and lower emissions, so applying the same principle to humans could yield similar benefits.

But to all my short kings out there, you're beautiful just the way you are.

Itty bitty Bob, you are beautiful the way you are right now.

But you want to probably go back to how you were.

After a few adjustments on my patent pending Resize erator, it's time to fix Triangle Bob.

I'll just keep firing until he looks a bit better, okay?

Oh, after running some polls, it seemed like our audience really wants us to focus on science videos about movies and games.

Right now, what is your favorite all time game and favorite all time movie?

Do you think that it would make for a fun Life Noggin video?

Let's see the Life Noggin audience's taste, shall we?
