Researchers have created a backpack that has a computer and medicines in it that can help even untrained soldiers save the lives of wounded troops. Wounded soldiers have a better chance of survival if they get help soon after being hurt and are quickly taken to a hospital or clinic. But soldiers who do not have medical training may not know how to help their injured friends.
Doctors and engineers have developed what they call an “intelligent backpack”.It has a computer and electronic measuring devices. The backpack also has robotic instruments and medicines ready to give to injured troops.
About 16 doctors and engineers from the University of Pittsburgh, Carnegie Mellon University and several other places are working on the project. The U. S. Department of Defense has given money to the project.
Ron Poropatich leads the project. He is a retired army surgeon. He says the backpack will help soldiers care for those who are injured. The devices included in the backpack can monitor a person^ heart rate and blood pressure. The robotic instruments can even tell whether the soldier has a collapsed lung.
The intelligent backpack's computer can compare information gathered about the injured soldier with thousands of similar cases, and quickly tell the best methods to use to save the soldier’s life.
Sometimes, it is not always possible to quickly remove the injured soldier from the battlefield.So,Dr. Poropatich says, the researchers hope to create a backpack that will have devices .that can keep a .soldier alive for a long time. Dr. Poropatich hopes the backpack and its instruments will be ready for testing animals in about three years.

Though many people tell us we can’t succeed, we need to hear others，opinions. I remember my high school English teacher telling me not to apply to Cornell University because they wouldn’t accept me and even if they did, I wouldn’t be able to do the work. I almost didn’t apply but a few days 
later I saw Ivan Goldfarb, a former teacher and asked him about Cornell. He said, “If you get in，then you go. You can do it.” His words made all the difference. I applied, and was accepted.
Too often we think it’s our role to put “reality” into someone’s life. We think it’s our job to protect people from the pain of failure and defeat. We think we must point out how bad the economy is and how horrible the job market is and how the sky is falling. We think that dreams are meant for others.
I say there are enough “realists” in the world. The world doesn’t need more negativity and impossible thinkers. The world needs more optimists，encouragers，and inspirers. The world needs more people to speak into the hearts of others and say “I believe in you.” “Follow your passion and live your purpose.” “The job market is not great but I believe you’ll find the right job for you.” and so on.
When it comes to encouragement, I know that everyone loves working for and with people who bring out the best in us. And while we'll always remember the negative people who told us we couldn’t accomplish something, we will always cherish and hold a special place in our heart for those who encouraged us.
Today I want to encourage you to be an encourager. So often the difference between success and failure is belief. And so often that belief is instilled (逐步灌输) in us by someone who encouraged us.

As confusion disappeared, we found freedom, time, and energy to do more of what we love. We started hiking more and added weekend and weeklong camping trips. In doing so，we realized more and more benefits of being outdoors.
The physical health benefits from being outside may be pretty obvious at first, but there are more than I realized. Studies have shown that besides the vitamin D intake, being outside can even reduce recovery and healing time. Activity outdoors can also have a higher fitness benefit than exercise done indoors.
A walk in the woods or even just a quick trip to a park can help reduce anxiety, improve short-term memory and reduce mental tiredness. Any time I need a boost in my mood, spending even five minutes in the sunshine will help. Imagine the benefits we receive from spending an entire day or even more outdoors.
As I’ve made it my preference to be outdoors, I find myself inspired and excited about life. Many people claim that their best ideas come to them in the shower. I have had the same happen when in nature. My creativity, confidence, and focus all increase after a hike or a weekend spent camping.
In between my my generation and the generation of my children, there has been an extreme decrease in the amount of time kids are spending more time indoors than ever before and shares shocking statistics of how little time kids get out VS hours of screen time each day. This has given rise to many negative consequences such as poorer physical and mental health.
However, as mentioned previously, all the benefits we as adults can receive from time spent outdoors, it is even better for our kids. It is clear that time in nature is good for both adults and children.
