The symptoms are small at first. You feel a little more tired than usual, perhaps a bit

forgetful. You shrug it off as stress. After a while, you feel a little more than tired.

You feel unwell. It's hard to tell what could be making you feel this way. Your

diet? A long-running cold? It doesn't happen all at once. Basic tasks are making you feel

like you're lost. Before you know it, it's all consuming.

But the doctor's standard tests don't show anything.

No one knows what's happening.

Inside your body, something has been accumulating.

There is toxic lead body, something has been accumulating.

There is toxic lead inside you, and it's poisoning you.

Ticking along, incrementing a little bit, a little bit more, a little bit more,

a little more damage, a little more damage.

And you feel like a conspiracy theorist if you talk to people like, neighbours are interested,

kind of, and they're like, oh, you're going on about that, okay.

Every American child is tested for this, so why isn't every British child tested for it too?

And they're failing at one of the most basic functions of government,

which is to protect its citizens.
