Fans reckon he's unlocked a new kind of evolution, but sceptics say he's dangerous. Amal Graafstra is a biohacker, upgrading the human body with technology to make it do more.
A self-described technologist, he has four RFID implants in his body that are about the size of a grain rice. These little bundles of wiring and casting of biocompatible glass sit under his skin and basically make him a little bit robot.
"You kinda forget that you have it, it becomes part of who you are within a matter of weeks," says Graafstra.
"I mean, you're sitting there and your kidneys are working hard for you, but you're not thinking about them.
"It's the same for me. I can just open my doors and log in to my computer without thinking about it."
Graafstra is the founder and CEO of Seattle-based company Dangerous Things, which sells implantable devices like the ones he has in his body to anyone who has upwards of a spare $40.

While the idea of biohacker kits that you can order direct to your home may seem a little unnatural to some, he argues that the idea is actually more natural than you may think.
"It's applying hacker methodology and ethic to biology, so arriving at solutions via unconventional means," says Graafstra.
"Evolution is selection and mutation, so we have some random mutation and some change. Either that's a good thing and we live, or it's a bad thing and we die.
"We've been opting out of selection for a long time ... we're deciding where we wanna go. It's a new kind of evolution."
