Gmail has a new Labs feature called Mail Goggles, which adds a safety check to late-night emails.
“When you enable Mail Goggles, it will check that you’re really sure you want to send that late night Friday email. And what better way to check than by making you solve a few simple math problems after you click send to verify you’re in the right state of mind?”
Could be a handy cross check if you’re feeling weary or had a few glasses.
