My eating habit distinguishes me from other people. In the morning I drink a cup of warm honey lemon liquid, which is really good for digesting. Then I eat some rye bread and drink a cup of plain milk. For lunch I eat chicken breast because it’s rich in protein. I also eat some vegetables such as spinach and lettuce. In the evening I eat fruit and yogurt. Sometimes I eat a bar of chocolate and then go to bed.
