Following my research and findings about random 'heroic' acts of selflessness, I have decided to focus on a very dangerous aspect of our society today.
Although it shouldn't be, our public transport system is a place of crime, from terrorist attacks, to stealing. Being enclosed in an underground train is often a place of unease. People keep to themselves and their belongings close by. I feel this is a perfect place to start advertising my campaign, to make people aware of what is going on around them... and to make them think about helping someone out.
There is also the boredom aspect of commuting, doing the same trip every working day... boredom ensues and you do anything to keep your mind occupied, including reading billboards and advertisements and consequently thinking about their content.
