How Long Should the Perfect Phone Call Last?

According to a new study, if your phone conversation includes chat about the weather, personal problems and current affairs, and last no more than nine minutes and 36 seconds, it's perfect!

9 minutes and 36 seconds!

After deciphering over 2,000 phone calls, researchers have come up with just the right recipe.

In your 9.36 minute conversation, three minutes should be spent on family and friends, one minute on personal problems, one minute on work or school, 42 seconds on current affairs and 24 seconds on the weather.

Complaining about your partner should just take 24 seconds, 12 seconds should be spent on celebrity gossip, one minute and 42 seconds laughing, one minute on other topics and 12 seconds saying nothing.

How long are your phone calls?  Who do you call the most?  Who do you avoid because they talk forever?
