Ну сократите текст чтобы легче было пересказывать

modern medicine is expensive, and pills usually have side effects. many people also argue that they treat the symptoms, not the cause of the problem for all these reasons, some doctors believe taking more and more medication can't be a good solution to health problems. some suggest exercise could be a more effective treatment for certain health conditions. between health and exercise isn't new lived around 2,500 years ago, when doctors in greece believed that good health depended on the body being in balance. the theory, which some people still believe today, is that if you are ill your body must be out of balance. to keep the body in balance, you must have the right diet and do the right amount of exercise- not too little and not too much. however, this relationship he doctors know that exercise reduces pain in people with illnesses such as arthritis. because strong muscles help support the bones and joints. exercise might also lead to a reduction in painful inflammation, or exercise helps swelling, in the body exercise can also help people with mental health problems, like depression. for example, some scientists think swimming in cold water in lakes and in the sea may be a better, and more effective treatment than antidepressants. they are not sure yet why it works exactly, but they see it does.
this would make treatment cheaper and probably safer for the individual. furthermore, cold water swimmers also get fewer infections. in particular, they don't seem to catch as many colds and flu as others. one of the reasons people get depressed is because they don't live near friends and family to talk to about problems. in fact, some countries now recognize loneliness as a big problem and cause of poor health. one solution may be to join a sports club. taking part in group activities can help people feel they belong and take their minds off their own problems.​

She has got long,  dark hair and brown eyes. We go in for sports together. On sundays we go to the cinema. Sveta likes to read books. So do I . I am happy to have such a friend. Предлагаю такое решение. Может там какая-то определённая лексика должна быть ? Вместо имени Света можно подставить любое другое имя ( твоей подружки) Переводится так. Это моя лучшая подруга . Её зовут Света. Она добрая, честная и вежливая. Света очень умная , она всегда мне с домашней работой. Света красивая.У неё длинные тёмные волосы и коричневые (карие) глаза. Мы вместе ходим заниматься спортом. По воскресеньям мы ходим в кинотеатр. Света любит читать книги. И я тоже. Я счастлива , что у меня есть такая подруга.

This is my best friend. First of all I want to tell you that my best friend's name is Irina and she is 15. She is the best person I have ever met.

A few  words about her appearance. Her height is nearly 149 cm. But she'd like to be a bit taller. Well, she is not slim but she is not fat either. 

Irina has a round face as everyone has, a bit long nose and big cheerful grey eyes. Her skin is a bit pale but she likes this fact, she doesn't like ruddy faces. She has no freckles as my friend Nina has. Her forehead is open. I think Irina has a charming smile. 

Her hair isn't very short but it's not long either. It is straight and black. Irina has rich hair.

I think that she looks like her father.

Irina is very active and creative, cheerful and curious. But the best thing is that she is reliable. We spend much time together. We go for a walk, we play tennis, watch TV, do things which we like.

I love my friend.

Это моя лучшая подруга. Прежде всего, я хочу сказать вам, что мою подруг зовут Ирина и ей 15. Она самый лучший человек, которого я когда-либо встречала.

Несколько слов об ее внешности. Её рост около 149 см. Но она хотела бы быть немного выше. Ну, она не худенькая, но и не толстая.
У Ирины круглое лицо, как и у всех, немного длинный нос и большие радостные серые глаза. Ее кожа немного бледная, но ей это нравится, она не любит румяные лица. У  нее нет веснушек как у моей подруги Нины. Ee лоб открытый.  Я думаю, у Ирины очаровательная улыбка.

Ее волосы не очень короткие, но это не длинные. Они прямые и  черные. У нее густые волосы.
Я думаю, что она похожа на своего отца.

Ирина очень активная и творческая, жизнерадостная и любознательная. Но самое главное - она надежная. Мы проводим много времени вместе. Мы ходим гулять, играем в теннис, смотрим телевизор, делаем вещи, которые нам нравятся.

Я люблю мою подругу.
