- Hosting another awareness program in your neighborhood is a perfect way to start an open dialogue about the preventive issue. It can also transform into something like a community-wide initiative to discourage unhealthy practices. This is indeed a time for someone like you to pass on the teachings of your ancestors. It's beginning to make room for such tough debates.
 - Your campaign could perhaps focus on educating your audience on a particular topic by communicating basic facts and presenting examples. This should help neighborhoods members participate in healthier discussions and raise public awareness. The preventive process will continue.
