I think a person will never starve to death, but will only die of laziness. If the class is full early, you can have breakfast in advance or buy some biscuits on the way. If you are too hungry, you won't care too much at all. A ten-minute break between classes is enough. If you starve to death because you have a full class in the morning, you are really lazy to the bone, so in this case, I think you must have died of laziness rather than starvation.

Any country in the world will have poor places. Although people there have little ability to feed themselves, they also know how to beg or other unacceptable ways to fill their stomachs. Hungry people can even lay down all their bodies for food, at least I think so. Therefore, even if some people live in poverty, they can always have a mouth to eat. Even if they die, various diseases lead to no money for treatment. But there are also many people who starve to death because of many objective conditions when their lives are difficult. But they are still very different from us. When we were students, we were busy at school every day. When we were in college, there were relatively few classes. So everyone basically eats breakfast before class in the morning. That's what I do. I basically have breakfast before class every day, and I am afraid of being hungry in the middle of class. Some people can't eat breakfast for other reasons, so they will eat it during self-study or other breaks. But at the same time, I can't avoid full classes in the morning and have no time to eat breakfast. Therefore, in this case, we can use our rest time to buy some food without starving, but if you are really too lazy to move and don't want to buy food, then you can only starve.

Therefore, under normal circumstances, we will not starve to death because we have a full class in the morning, unless you are particularly lazy.
