If you try these things, they can help people to avoid back pain, which is very common. Excercising, losing weight and maintaining good posture are important. Practice standing tall, with your head up and your shoulders back and sitting straight, but not slouching. Slouching is bad for the spine. It's also bad for blood circulation. So keep your back against the back of the chair, keep your feet flat on the floor and keep your knees slightly higher than your hips.

This exercise consist in write a short letter to Julia's mom, who is sad because of her daugther is studying far away...so!, here is the letter...

Dear mom!

How are you?

I'm really happy because of receive your letter! Sincerely, I'm missing you too, but I know that you and dad are good in home! Maybe dad seems kind of depressed cause' his football team lose few days ago, don't worry about it. Regarding my room, come on mom!...It was always in the same way because I just have my bed and the old T.V., anyway...I love it! thanks for take care of that!

I have new friends here, but I still miss my best friends. Pete Dove is that guy who was always complaining about me? It's good for him that finally is working with an accounting firm, but I don't like that kind of work. I cannot understand why is he living with his parents if he could pay an apartment, well...give him my greetings.

I found a part-time job here in the city, the salary is good and I'm learning too much about the activities. I've been saving money, so...I could visit you one time per month but believe me...I'm not thinking about come back to home I have new plans, and for now, everything is going very well...I love you mom!

Take care!

Julia
