In the year 2070, most of you will be more than 60 years old. The good news is that travel might become smarter by that time. European airline（航空公司）easyJet has made some predictions and released （发布）easyJet 2070-The Future Travel Report. Let's take a look at some cool ideas.
Heartbeat（心跳）passport
Paper passports will be a thing of the past. You will use " heartbeat passports" instead. According to experts, everyone's heartbeat is different. So the data（数据）will be used to tell who you are.
More comfortable flight（飞行）
The seats on the plane will no longer be " one size fits all" . You'll actually be able to book （预定）a seat according to your body type（型）. The seat might even be able to cool or warm you to your preferred temperature. There will also be no more screens on the back of your seats. A future device （设备）could show movies straight in front of your eyes.
Printed clothes and food
If you hate packing clothes, you may not need to do it in the future. Before you fly, you will have a body scan（扫描）. When you arrive, you'll find a wardrobe（衣橱）filled with 3 D-printed clothes in your size. When you leave, the clothes can be recycled and reprinted for the next person. You can also 3 D print whatever you want to eat.
Bring history back to life
If you like to visit places of interest, augmented reality（增强现实）will change the game. Wearing a headset（头戴式耳机）, you can see what happened there, such as a famous war.
