My simple Life

Why should we do exercise everyday?
I think the following statements are good answers.
1.
Physical activity boosts levels of high-density lipoproteins, or HDL, the so-called good cholesterol, by as much as 20 percent. HDL helps rid the body of low-density lipoproteins, or LDL, the artery-clogging kind. Studies show that HDL can even pick up cholesterol deposited in arteries and move it to where it won't do harm. Another benefit to the arteries: The level of fat particles in the blood, called triglycerides, falls by as much as 40 percent after a vigorous workout. Exercising converts triglycerides into fatty acids -- the form in which fat can be burned for energy. You burn stored fat each and every time you work out -- the key to keeping weight off. Plus you lower your level of triglycerides in the blood. And the lower your triglyceride level, studies show, the lower your risk of heart disease. 
2.
The moment you begin exercising, your heart starts pounding and your blood pressure surges, sweeping disease-fighting immune cells out into the blood, where they're able to detect troublemakers like cold or flu viruses. Studies show that people who exercise have 40 to 50 percent fewer sick days than their sit-around-and-do-nothing counterparts. 
ps. I cited the two reasons from http://www.rd.com/content/5-great-reasons-to-get-moving/



That why I like to do exercise, because it benefits me.
I am willing to show you and benefit you as well.
Besides, I learn a lot from reading "healthy issue".
However I dont know where many proper nouns. 
Therefore, I note them in the following and try to memorize them.
I hope next time I won't need to look them up in the dictionary when I see them again.
