4). Believe that you are able to change.

I used to roll my eyes many times before I could get up. Recently, things have changed after I read stories like this one, "Getting up early changed my life". Here are the benefits I've seen so far from changing my workout routine.

    I have more energy

    As I said, I've been a sleepy person while I still love sleeping. I now have an extra burst of energy. I'm less weak in the office, and my brain is more attentive and ready to work. Once, {#blank#}1{#/blank#}, not even coffee could get me ready for the day. But now a good workout can.

I have more confidence

    The enough energy rolled into more confidence. I feel better after a workout. Also, after getting especially sweaty, I have to take time to shower, of course. {#blank#}2{#/blank#}.

    {#blank#}3{#/blank#}.

    Getting up earlier and using my energy earlier make me so unbelievably ready for bed by the end of the day. My old routine would consist of getting up at the last possible minute before work and being absolutely exhausted to try to fall asleep. Have you ever felt so tired that you can't fall asleep? {#blank#}4{#/blank#}.

    I have more time

    {#blank#}5{#/blank#}. Now that I've shifted my schedule, I have a little more time after work to take care of myself, whether that's spending time with friends, cooking a healthier meal, reading and studying, or even just watching a movie.

A. I sleep better

B. I'm more consistent

C. It sound ridiculous, but it happens

D. I'd have to skip my workout -in favor of a social life

E. I had a hard time to try to wake up physically and mentally

F. Speaking of that old routine, my days used to consist of work and sleep

G. This means I go through my full morning routine instead of just rolling out of bed

A Diet Without Enough Protein Can Cause Depression

    Depression is a condition so common, the World Health Organization (WHO) calls it "a leading cause of disability."

    Difficulty in falling asleep, loss of appetite, and loss of ability to concentrate are just a few of the other effects of depression. WHO estimates that worldwide, at any one time, 350 million people suffer from the condition. While life events such as the loss of a spouse or a job may create a happening of depression, many cases come from within and are not caused by a life event.

    Now scientists are working on a new aspect of cure: nutrition. {#blank#}1{#/blank#} The Indian Journal of Psychiartry reports that both before and during a happening of depression, those with the condition will show a "poor appetite…" {#blank#}2{#/blank#} Many cases of depression, if not most cases, affect those who don't eat properly.

    So what does protein have to do with all this? It all comes down to amino acids (氨基酸). Proteins are made up of amino acids, chemicals known as the "building blocks of life." There are 20 different amino acids. {#blank#}3{#/blank#}

    Both the human brain and nervous system use amino acids as a substance that creates a signal from one brain cell to another or one nerve cell to another, thus relaying information between the cells. What the final result then? {#blank#}4{#/blank#}

    Since amino acids make up protein, a diet which lacks in protein will cause weaker communication between the brain cells. This lessens the signal being sent from one brain cell to the next during a thought. {#blank#}5{#/blank#} This is why depression can often express itself as anger or aggression.

A. The ultimate effect is how we think.

B. Don't ruin your appetite by eating between meals.

C. Skipping meals itself can create a depressed mood.

D. A new research suggests that nutrition can lessen some of the risks of depression.

E. India is perhaps the world's leader in researching the connection between diet and depression.

F. Many of them are made by the human body, but nine others, the "essential" amino acids, must be eaten in one's diet.

G. The process can lead to twisted signals, which can not only lead to depression, but also, according to many scientists, aggression.
