Well, if you use Google’s gmail, the company is trying to help you stop this behavior. Google Labs has just developed a new feature for gmail – Mail Goggles – that, when enabled, will ask you a series of math questions before sending your email. The idea is that if you are not in the right state of mind to solve a few math problems, you might want to reconsider sending the email you just wrote.

Now, quit sending those emails that you later regret.
