But yeah, it's a huge challenge for the world and probably the thing that invisibly affects us when we don't think about.

Or even the idea I talk about that if you're in a place with air pollution, if you're outside running or cycling, you could be doing more harm to your health doing that than actually the good of the exercise because of the pollution going through your system.

Yeah.

I brought it up in the book because I think it's something that people do feel it's beyond their control.

They might follow like the air quality indicator, but we need to have like collective action to actually say this is a problem.

It matters to health.

And this is why.

And these are solutions.

And these are places trying to do things differently.

And if we don't take these measures, we could into a place where too many kids are having, you know,

very severe asthma episodes because actually they're being triggered by that and you can have as many hospitals as you want, but if you're not fixing the air, how do you actually manage it?

So, yeah.

Yeah, so I think I talk about water because I guess people reading it might be in a place where they have great tap water and they can drink it.

I'm lucky in Scotland.

So Scottish water is publicly owned.

It provides basically kind of free tap water throughout the country.

There's water stations you can go to in parks.

It's not like Brussels and Paris, which have sparkling water stations.

You can go kind of get your...

your water.
