Очень важно вести здоровый образ жизни. Каждый человек хочет прожить, как можно дольше, не болеть и всегда хорошо выглядеть. Для этого необходимо есть полезную пищу, заниматься спортом, больше гулять и иметь активную жизненную позицию.

Лучше всего с самого раннего детства вырабатывать режим дня и следить за своим питанием. Большое значение в жизни человека занимает сон, поэтому важно высыпаться и ложиться спать и просыпаться по утрам в одно и то же время. Полезно завтракать кашами, есть рыбу, овощи, и молочные продукты. Важно ограничивать себя в сладком и газированных напитках.
