It affects me because when you are reading a book about subways and a gas attack, when I ride on the subway I picture myself sitting and not having a way to get out. Sometimes the trains are crowded, you never know who is on and what is happening in each station. Now that I go on subways, I stay myself up in case of any emergency, before I use to get on the subway and fall asleep. Now reading this book makes me want to be more alert on everything, keep on eye on the stations and listen to the person who speaks on the radio. Reading all types of precautions is always helpful, to know what’s going on in the station you're getting off.
