And you, my friend, have just stepped into a world of solutions.
I'm Mayra Anubi, and every week we travel everywhere to discover new ideas that are making our planet a better place.
Now, speaking about traveling, this week we're catching a medical train in South Africa and then hopping on a truck in the UK to find out about clever ways to deliver affordable health care directly to people who need it most.
When I'm unwell, I call the doctor for an appointment or head directly to a hospital that's just about 10 minutes away from me.
And getting a checkup or medication is also affordable.
But I know I'm lucky and this isn't the reality.
For many people across the world, healthcare can be very expensive and difficult.
Difficult to access.
The World Health Organization currently estimates that more than half of the world's population doesn't have access to essential health services.
This sent me on a journey to find solutions that are helping to bridge that gap.
And I found something in South Africa.
South Africa is interesting.
It's considered to have one of the best health care systems on the continent.
But a lot of that care is private healthcare, which can be very expensive.
In fact, 85% of the population rely heavily on public medical care.
Also, people in remote parts of the country have to travel long distances to get treatment.
But there's one idea that's been working to get public health back on the rails.
