BBC Future has brought you in-depth and rigorous stories to help you navigate the current pandemic, but we know that’s not all you want to read. So now we’re dedicating a series to help you escape. We’ll be revisiting our most popular features from the last three years in our Lockdown Longreads.

You’ll find everything from the story about the world’s greatest space mission to the truth about whether our cats really love us, the epic hunt to bring illegal fishermen to justice and the small team which brings long-buried World War Two tanks back to life. What you won’t find is any reference to, well, you-know-what. Enjoy.

Nestled in a grassy valley of north-western Namibia, Opuwo may seem like a crumbling relic of colonial history. With a population of just 12,000, the town is so small that it would take less than a minute to drive from the road sign on one side of town to the shanty villages on other. Along the way, you would see a hotchpotch collection of administrative offices, a couple of schools, a hospital and a handful of supermarkets and petrol stations.

For many of the people living in the surrounding valley, however, this small town is also the first taste of modern life. The capital of the Kunene region, Opuwo lies in the heartland of the Himba people, a semi-nomadic people who spend their days herding cattle. Long after many of the world’s other indigenous populations had begun to migrate to cities, the Himba had mostly avoided contact with modern culture, quietly continuing their traditional life. But that is slowly changing, with younger generations feeling the draw of Opuwo, where they will encounter cars, brick buildings, and writing for the first time.

How does the human mind cope with all those novelties and new sensations? By studying people like the Himba, at the start of their journey into modernity, scientists are now hoping to understand the ways that modern life may have altered all of our minds. The results so far are fascinating, documenting a striking change in our visual focus and attention. The Himba people, it seems, don’t see the world like the rest of us.
