The sick

If one wants to collect money for a charity action, here's an idea which you should also direct it to: People which suffer from sanctions imposed on their state on the base of dubious reasons - if you're dependent on medication, you'll get your troubles obtaining it because lots of the patents for active agents and drugs are in possession of companies stationed in Europe or the United States.
The more specific your disease, the more troubles to get a hold of your medicine - and as well as the price.
Being santioned by those countries so equals a death sentence, if not that then at least a noticeable decrease in the course of your progressing disease.
