Technology can also save your fingers


Though this is a little off-topic, I always like to see whenever human minds are dedicated to reduce the possibility of accidents in some regular tasks we do in our lives.

One good example is this video: around 60,000 accidents using table saws are registered in the US every year, with 3,000 people taking their fingers off every year. This guy has developped a technology to prevent that, and he is ready to use his own finger to test the technology.

See the video:

Amazing, isn't it?
