Middle-aged, overweight men aren’t the only ones who should be worried about heart attacks. In fact, women under 55 are equally (or more!) likely to suffer from heart disease, according to a study published in the Journal of the American College of Cardiology. Despite the risks, a 2016 statement issued by the American Heart Association (AHA) has revealed that women are often undertreated for this deadly condition. The reason? Most fail to recognize the silent signs of a heart attack that apply exclusively to females.

While once considered the height of luxury, airplane travel has taken—to put it lightly—a serious nosedive over the past 30 years.
