Our happy hour fact to amaze your drinking buddies with.

The average amount of time a woman can keep a secret is 47 hours and 15 minutes.

A survey of 3,000 females between the ages of 18 and 65 also found 40 percent conceding they had no ability to keep any secret, no matter how sensitive. About half said that alcohol loosens their lips, and two-thirds feel guilty after spilling the beans.

Nevertheless, 83 percent of respondents also deemed themselves "100 percent" trustworthy.

While they weren't surveyed, we're pretty sure the average guy can keep it in the vault for more than 47 hours. If for no other reason than because he's forgotten all about it by then.
