SURGERY
Treatment of injuries or traumas by operative techniques is the subject of surgery.
The surgeon has always been an integral part of medical science. Early medical texts are devoted chiefly to records of surgical cases. Strangely, however, the great advances in surgery have been dependent on medical discoveries in other fields. These advances include the discovery of ether anesthesia by Morton and Long in 1847; the discovery of the principle of antisepsis by Joseph Lister in 1865—87, and the application of rubber gloves introduced by Halstead. The use of blood transfusion, the control of fluid in the body and the use of drugs for various symptoms have also aided success in surgery.
Not many years have passed since the time when few surgeons dared to invade the interior of the abdomen.
Today every portion of the human body has been invaded successfully. The surgery of today is called physiological surgery and is aimed at restoring (восстановление) normal function of various organs and tissues when these functions have failed.

Dear Paul,
Thank you for your letter! I'm glad to hear that you've passed your driving test! Congratulations!
I'm sorry I haven't written for such a long time. I've been really busy with my new project. By the way, thank you for your brilliant idea. I really had the best presentation last time. I really appreciated your advice.
As for your question, I think all you have to do is just regular exercises. Don't be lazy and try to find at least 20-30 minutes for your health every day. There is a rule of 30 minutes a day: if you do something at least 30 minutes a day you will have a result at the end of the week. For example, if you read 50 pages during this time, at the end of the week you'll have total of about 350 pages. If we say that we don't have enough time for it (as we usually do) we have 0 result at the end of the week. Besides, they say that it takes 21 days to form a new habit. So all you have to do is to take the bull by the horns and try it for just 3 weeks.
Unfortunately, I need to come back to my project. I hope my advice was helpful.
Hope to hear from you soon.
Take care,
Victor
