Americans are using only 77 percent of their paid time off, and the decline is partially tied to recent economic problems. Use of vacation days is at the lowest point in four decades. For example, 222 million such days remained unredeemed in 2015, according to the U.S. Travel Association. This can be used as a strong argument that if you are going to take a break from everyday life, you need it to be a real break. Go to a place where no one can reach you and you are not tempted to use your phone or any other electronic device. You need to truly unplug and unwind in order to relax and recharge.
