Hi, I very much wish you feel good. Yes, your doctors and friends are right. You need to play sports and lead a healthy lifestyle. Eat only good, nutritious food. For example, meat, milk, fruits, vegetables. Drink more mineral water and natural juices. Do not drink alcohol and do not smoke cigarettes. Go to the gym every day or at least 3 times a week. Walk in the evenings, breathe the fresh air. Do not sit at the computer a lot and do not often use the phone, it is harmful to the eyes.
