When I write of loneliness, I guess you don't understand a bit of what I meant. Here's the catch...

There are people who isolate themselves from social gathering, they enjoy the alone time. They don't want relationships from family, friends, per groups, etc these people have higher risk of premature death, you can research if you want.

Loneliness is a silent killer just like Aids, you may not know it until you experience it. I was once there, so I write from experience. Hosting a contest wouldn't be bad afterall, but make sure to understand the topic so well to help you generate your hints...
