Enable this lab before you head out for the night (Settings > Labs > search "Mail Goggles") in order to prevent embarassing or incriminating emails from being sent to friends, lovers, or exes. The lab will force you to solve a few math equations before emails can be delivered, the premise being that if you're too drunk to solve them, then maybe you'll move on to more pressing matters . . . like downing some water, food, or getting to bed.
