Remember a few posts back I made a little life simulation invention idea? I could improve on that. Some could have a chance of not getting a job, and will be in poverty. If you run out of food, you lose health. If your kids hang out around other kids, there will be a slight chance that a new common cold/flu will be made, but if one kid has the flu, one kid will get the flu also. They will have it for 7 days, and have less health. Adults can only get sick from kids. If you lose all of your health, you 'die'. This is one of the only reasons for the consumer to come and bring them back to life (re-activate them).
What really sparked my interest was the Nao robot. Check it out.
