As an Olympic gymnast, Simone Biles knows a thing or two about balance.

So when an internet troll called out the four-time gold medalist for trading the uneven bars for the beach, she had the perfect response.

“Seems like u have partied non stop for a year #trash #unfollow #suckya** rolemodel,” the Instagram user wrote in a now-deleted comment to a snap of Biles sunning herself in Hawaii.

The 20-year-old champion flipped it back with: “Talk to me when you train for 14 years and earn 5 Olympic Medals … My year off is well deserved! Take a couple seats.”

We all deserve a vacation from the daily grind to reboot, just as much as Biles does.

“Research shows that a third of workers say that they are extremely stressed out,” Michael Erwin, senior career advisor at CareerBuilder.com, told Moneyish. “So taking vacation is a great way for out you take a step away from your job and recharge, and get those creative juices working again, so when you come back, you’re feeling excited about being there, and you’re going to be a more productive worker.”

Yet a recent Associated Press poll found that 43% of Americans won’t take a vacation this summer. Last year, 55% didn’t take all of their paid vacay, and those that did take off didn’t really get away, since 61% admitted to still working or checking in with the office. In fact, Americans leave 662 million vacation days worth $66.4 billion unused each year, according to Project: Time Off (which is sponsored by the U.S. Travel Association). 

Why is everyone staying put? About half can’t afford to take a trip, the AP found in its report, especially since 41% of working Americans said they don’t get paid vacation time their employers. But another 11% said they can’t miss the time off from work.

Plus, humblebrags about working too hard to have any fun has become the new status symbol, according to a report released earlier this year that found being busy has become the new aspirational American status symbol. 

But research shows that we can’t afford to skip getting a little R&R. Here are four reasons to spend some time away from your desk.

It’s healthy. More than half of Americans (53%) are burned out and overworked, according to a recent survey by Staples AdvantageAnd the cure for that is rest. Researchers from the State University of New York at Oswego found men ages 35 to 57 who didn’t take at least one week-long vacation per year suffered a 30% greater risk of dying from heart disease. Work martyrs are also at risk for stress-related issues like high blood pressure, type 2 diabetes, and obesity. 

The longer you work, the less productive you get. Research shows that employee productively drops after a 50-hour work-week, and plummets after 55 hours. And an internal study done by the Ernst & Young accounting firm found that for each additional 10 hours that an employee took for vacation, his or her performance review was 8% higher the next year. 

You could make more money. Those who take all of their vacay have a 6.5% better chance of getting a promotion or a raise than those who don’t take 11 or more days of their paid time, according to Project: Time Off. So work martyrs don’t have anything to lose by getting away – but could have everything to gain.

Vacations inspire great ideas. Getting away from the daily grind can give you the next Big Idea to bring back to work. A 2008 study found that multicultural experiences enhance creativity and generate ideas. Howard Schultz had the brainstorm for Starbucks during a 1983 trip to ItalyLin-Manuel Miranda came up with the Broadway smash “Hamilton” while vacationing in Mexico to recharge from his previous hit “In The Heights.”
