Five awkward emails Google's 'Undo Send' will save you from

From the unintended reply all to the email bitching about your boss that you accidentally send to your boss, here's how we can now be saved

The wheel, the telegram and now, Google's "Undo Send" email feature. There's nothing like an invention that truly changes the fabric of life. Even better are those that save us: hydraulic braking, say, or rehab.

This is the news that the tech giant is rolling out a feature allowing users to pull back emails - up to 30 seconds after hitting send. The feature has been around for a while, but hidden in Google's labs section.
