Do you consider yourself lazy? The stereotypes say we're lazy, but Americans are NOT good at taking vacation days.  But according to a new study from Metro , even if you don't take a lot of actual vacations . . . you really do need to take a day off every few months.

The study found that it's actually bad to go more than 62 days without a vacation day.  That's the average tipping point when people go from being, quote, "fresh and focused [to] anxious, aggressive, and ill."

So if you are grumpy all you really need is a vacation.
