Keyboards can Recognize Heartbeats

Yes it can, I personally tested it, well, you can say that I discovered it.

Here how it works:

1. Set down in front of your PC.
2. Put your right cheek on the keyboard touching the space bar and some other keys.
3. Start listening to your heartbeats.



Note: this is tested on an HP PC, windows XP. It is not guaranteed to work on laptops.
