It’s ingenious, really.

To prevent those e-mails that you’re just not that stable enough to send, Google can now give you a test to ensure that you know what you’re doing.

You better know your math.

The Mail Goggles test feature in Gmail gives you 60 seconds to solve five math questions. You can enact this feature whenever you want — the automatic settings are from 10 p.m. to 4 a.m. on Friday and Saturday nights for those times at the piano bar. Gmail wants to make sure you don’t send that angry e-mail to your boss when you get home.

As you can see above, not all those questions aren’t that easy (except the repeated one). And the time limit is intimidating. There are five skill levels you can chose — above is level 3.

Just another example of how Google is saving (or taking over) the world.
