Breakfast in Italy

How can the Italians have a so small amount of breakfast, and still make it through the day. I know that if I only had a biscuit and a glass of milk, I would pretty much die at the middle of the day, and my corpse would probably be long gone at night. Some of them said that it was because they didn't have enough time to get ready in the morning. So I asked them what time they used to wake up, and they said "at around 06:00 am". If you wake up at 06:00 am and you don't have enough time for breakfast, what do you do the rest of the time.
