Black Swan by Old-Man-George. They became a modern metaphor for shock when economist Nassim Taleb wrote about the historic moment when early Europeans arriving in Australia were blown away by the sight of swans with dark feathers.
I read somewhere that swans mate for life. And when their mate dies they can die from a broken heart. So i thought 2 swans or even a couples tattoo of swans would be awesome. So now it is on my list of tattoos.
