Or build character and don’t start typing in the first place

ANYONE who has spent more than a few minutes over the last couple of weeks trolling tech blogs or cocktail lounges has probably heard about Mail Goggles, a new feature on Google’s Gmail program that is intended to help stamp out a scourge that few knew existed: late-night drunken e-mailing.
The experimental program requires any user who enables the function to perform five simple math problems in 60 seconds before sending e-mails between 10 p.m. and 4 a.m. on weekends. That time frame apparently corresponds to the gap between cocktail No. 1 and cocktail No. 4, when tapping out an e-mail message to an ex or a co-worker can seem like the equivalent of bungee jumping without a cord.
