I just found out that gold is being mined from the New York City sewers.

With 20 million people living in the city, whenever someone showers or washes their hands with jewellery on, tiny flecks of gold flush down into the sewer.

Then using chemical detergents they can filter out the effluence and refine the raw gold used to make New York's finest jewellery.

Thanks. Now I'll taste that every time I lick my gold tooth.
