I'm Rory Stewart and I grew up wanting to be a hero and I'm still fascinated by the ideas of heroism.

In my new series, I'm taking in the long sweep of history from Achilles to Zelensky and asking, what is a hero?

Simply doing your job, being a decent human being.

A true hero is someone who just kind of shines by

their own light and that light is to be recognised by others. The long history of heroism with me,

Rory Stewart. Listen on BBC Sounds. Hello and thanks for downloading the more or less podcast.

We're the program that looks at the numbers in the news, life and communal

work environments. And I'm Lizzie McNeil. Now, we're recording this in the BBC's offices in

Broadcasting House in London, and I've got a complaint to make. It's the middle of summer,

but for some reason, the office's temperature has been set to the ideal resting temperature of a bag of frozen peas.

I could be exaggerating. Whatever, it's chilly.

At least, I think it is.

Although some of my colleagues are wearing shorts, it's madness.

But it's not just me that thinks this.

In fact, summertime in the office is jokingly known as women's winter,

as demonstrated here in a viral video from comedy group Dropout.

When spring turns to summer and there's blossom on the trees, the office air duct turned to ice

and all the women freeze. I don't know. I'm pretty comfortable.

A quick Google will show you plenty of headlines talking about this and claiming that

women prefer temperatures up to 2.5 degrees warmer than men.

But is this true? And if so, why?

The research is quite clear on this. We have seen that women have a higher prevalence of being uncomfortable because they are cold in the office place.
