We’re living in the future, folks. Really, look around you: we have the biggest collection of knowledge in history available for free, at our fingertips — and we can access it in a car, at 70 miles per hour, without any wires. Planes can transport us across the country, or across the world, in hours (or, as Louis CK so wonderfully puts it, “You’re sitting in a chair.. in the sky.) Technology that changed the world and cost many thousands of dollars just 20 years ago now comes at a fraction of the price, and at a fraction of the size. Everything is amazing.

The thing in the video above (which’ll be announced at CES next week) is just one more example. It’s an Electrocardiography device (or ECG.) You know those things in hospitals that (hopefully) go ” Boop, boop,boop” to the beat of someone’s heart? Yeah — it’s one of those.. for the iPhone. Pop on the iphonECG case, open the monitoring app, and plop it up against your heart. Tada! It’s an ECG. For comparison, here’s one of the first ECG devices ever created. Insanity.
