People aren't going to die from 3 days without food, but it will be very uncomfortable. People have died in wealthy countries due to dehydration after natural disasters, it happened in Katrina. People were without fresh water for up to 5 days in that case. As I said, you should expect to fend for yourself for 3 days. If you have no food or water or medical supplies ready, how do you expect to aid and assist people who need help? My experiences from New Zealand have led me to believe that if there's a magnitude 8 earthquake under a major city, which is entirely possible, that unless you are seriously injured you will be expected to look after yourself for several days.
