Google’s new e-mail-related program, Mail Goggles, was received with enthusiasm by the company’s users, as it is a fun and innovative way of checking the users’ state. The program requires users to solve five math problems in 60 seconds or less in order to send your message.

It was designed to keep Google’s users, while being drunk or extremely tired, from sending certain messages that they might regret in the morning. Once one gets one of the math problems wrong, the message "Water and bed for you" will appear on the screen.

Jon Perlow, Gmail engineer and author of the Mail Goggles extension, came with the idea after experiencing a similar situation with his ex-girlfriend. He decided to develop something that would assist others to avoid such incidents. “Hopefully Mail Goggles will prevent many of you out there from sending messages you wish you hadn't. Like that late night memo -- I mean mission statement -- to the entire firm,” explained Perlow.

The system needs to be activated from the user’s page and can be opted out at any moment. Users can specify the days and exact time that they expect Goggles to kick in and also the difficulty of the math problems, 1 being the easiest and 5 being the most difficult.

Of course there are still many ways that people can make a fool of themselves, whether it is a different e-mail address, the same Gmail account accessed from a mobile device (which are not covered at this point) or simply a phone call.
