We're very excited to say that this video is sponsored by Nautilus.

If you love learning and art, just like Life Noggin does, Stay tuned at the end of the video to hear more about the cool work done by Nautilus and how viewers of Life Noggin can save big this adorable video to welcome to what's Gonna Kill Me?

The game show where we ask our contestants.

Not to freak you out or anything, but the world is full of things that can kill you.

From natural disasters to illnesses to wild animals.

And I'm not talking about large predators like lions and crocodiles.

Those only kill a couple hundred to a thousand people a year.

The world's deadliest creature is much, much smaller.

Okay guys, what's the world's deadliest creature?

Triangle Bob we were looking for mosquito, not a giant logo sign.

We'll talk more about the world's deadliest killers after a brief word from our intro.

Mosquitoes are responsible for the death of over 1 million people each year.

These include viruses like dengue, West Nile and Zika, as well as parasites like the one that causes malaria.

In fact, malaria is responsible for the majority of mosquito related deaths.

The parasite infects blood cells, which can result in blood abnormalities or organ failure.

And while preventative measures like insecticides and window scre have largely reduced the number of cases, malaria killed over 600,000 people just in 2020.

But there's other diseases with an even higher death toll.

In the past 200 years, tuberculosis has killed over 1 billion people, making it the deadliest infectious disease in history.

Each year it's responsible for the death of about 1.6 million people.

Scientists believe that a third of the world's population are infected with a dormant form of this bacteria.

But it can be reactivated and spread through coughing and sneezing.

And those with a weakened immune system are most at risk.

There have also been drug resistant tuberculosis cases documented all over the world, making treatment all the more complicated.

But that's still not the world's deadliest killer.

The that award goes to an unavoidable process that all living things aging.

About 100,000 people die from age related causes every day.

That's because as you age, your body goes through lots of changes, like a decline in the function of organs or the immune system.

Eventually an organ fails or a disease is acquired and that results in death.

Fighting age related diseases and aging in general is super important.

We need to be putting a few more resources into treating that.

For the top two deadliest diseases in the world, heart disease and cancer, aging is one of the most important risk factors.

This is due to your arteries becoming harder and accumulating fatty deposits as you age and your cells developing more and more genetic mutations over your lifetime.

At least it won't be at the hands or the teeth of a lion.

So I wanted to try something in the Ask me a question that you want to see as a Life Noggin video.

The three questions that are the most liked will be added to our video list.

Pending the questions are appropriate, I reserve the right to, you know, not make them, but

Anyone who sees the value in using visuals or a unique idea to help people learn is a friend of Life Noggin.

That's why I was, I guess you could say overly excited when I got the chance to work with today's sponsor, Nautilus.

If you're looking to shake up how you learn about the world beyond just YouTube, check this out.

Nautilus Nodalis explores big ideas in science.

Its stories present ideas that will be debated long into the future and as a result has established itself as the foremost literary science magazine.

You can join as a digital only member or print to receive six beautifully illustrated, award winning collectible editions that are a staple of any respectable home library.

One of my favorite parts is that in addition to full access to all the stories in Nautilus, members receive benefits like priority access to events, exclusive products and product discounts.

For example, Nautilus recently produced a line of ocean science inspired merch with Australian streetwear company Jungles.

Quotes for the collection were provided by Roger Payne, the legendary biologist and environmentalist who discovered and first recorded humpback whale songs in 1967.

All proceeds were donated to Nautilus Ocean Conservation Fund.

It's this merger of art, culture, science and discovery that make Nautilus stand apart from the traditional science news sources.
