But in a pinch, I'm pretty sure I've got this too.

I do country lane driving, which means that I'm very good at the fast reactions if there's something because a lot of...

English country lanes, you can drive up to 60 miles an hour, but they are essentially the width of one car.

So if there's something coming towards you from the opposite direction, you need to have fast reaction times.

So that's what I'm trained on.

I feel like we've got three fire truck drivers here.

Thank you, listeners, once again for all of your messages.

We do love them.

Still to come on the show, joining the dots between Ebola and the evolution of flight.

Plus, we solve the mystery of the Bermuda Triangle.

You're welcome.

Earlier, I asked you, what do dung beetles use to help them navigate the plains of the African savannah?

And the answer is C, the Milky Way.

Scientists working in South Africa discovered that dung beetles are the first known animals to use the Milky Way as a compass.

Researchers tracked beetles' movements out on the savannah and indoors under an artificial night sky.

When they blocked the beetles' view of the sky, the insects immediately lost their sense of direction.

Further investigation found the beetles weren't using stars, but the soft, glowing bands of light that come from our galaxy, the Milky Way, comparing the brighter and darker patches to move in a straight line.

For a creature whose survival depends on a ball of dung, that's pretty impressive.

We are now at the part of the show where one of our curious listeners sends in a question and we get an expert on speed dial to answer it.

It's time for Ask the Unexpected.
