Shhh, we just can't talk about that.

Omigosh: We. Just. Don't. Do. That.

If you haven't guessed, we're talking about taboos.

Taboos are part of every culture, every family, every circle of friends.

We're planning to explore taboos in an upcoming series of stories. We'd like to hear from our audience about taboos they've encountered in the world of global health and development.

So tell us: What global taboos should we consider? Share your ideas in the tool below.

Would you rather raise your kids in Europe or Africa?

That's the question that Carl Manlan faced. Carl, who's from the Ivory Coast, and his wife, Lelani, who's from South Africa, started their family in Geneva, Switzerland, where they were working at the time. They have two children, a daughter named Claire, born in May 2012, and a son named Liam, born in September 2014.

Geneva is a great place to raise kids, Carl says. "Lots of opportunities to stimulate kids outside of the home, playgrounds for kids. You don't really find that in most cities in Africa."

Do trees grow from seeds that goats eat and later expel?

That is a question that has long bedeviled ecologists.

Let's say it's a small seed. The goat will swallow it, poop it out and a tree could sprout.

But what if it's a sizable seed? It probably wouldn't make it through the goat's digestive tract intact. And so ... no tree.

Refugees make headlines. Internally displaced people don't.

Maybe their plight eludes the limelight because, unlike refugees, they don't cross international borders ... or seek to enter the United States or Western Europe, where people debate how many of them to let in ... or undertake harrowing voyages across the Mediterranean.

And maybe it's because of their official label. "Internally displaced persons" (also known as IDPs) sounds vague and a bit confusing, as if they were lost inside themselves.

Some schoolkids might be happy if their school were knocked down.

Not in Nairobi.

On May 15, a group of primary school students sat at desks in the center of a main road to block traffic. Along with their parents, they were protesting the demolition of their school, the Kenyatta Golf Course Academy, over the weekend.
