Google’s new test feature, “Mail Goggles,” part of the free Gmail service, can save those who send the occasional (or frequent) tipsy (or inebriated) email a whole lot of regret and an even bigger headache in the morning.

When the goggles are active, they will require you to solve a few easy math problems before you hit “send.” Basically Google’s logic is that if you’re sober enough to solve the problems, then you’re sober enough to deal with the repercussions of your actions.

Ha!
