THE DANISH TRAVEL AGENCY Spies Rejser has found a solution to the country’s falling birth rate: they urged Danish moms to send their adult kids on sunny, healthy, baby-making vacations.

According to Spies Rejser, sunshine and exercise will increase the couple’s sex drive and consequently improve their chances of conception, making Denmark and grandmas very, very happy.

Although hilarious, the ad campaign tackles a serious problem: the fertility rate in Denmark has fallen from 1.9 births per woman in 2010 to 1.7 in 2013.

So, let your mom pay for your sunny vacations and, as a token of your gratitude, get busy!
