They don't need mouth to mouth

A simple show of kindness can be a breath of fresh air to someone who is feeling smothered by all the issues at hand they may be dealing with. Be kind to everyone you encounter throughout your day for you have no idea the problems they may be facing. A smile as you walk by will naturally subconsciously cause them to smile back which may distract them long enough to let them take in a breath of fresh air. If they take in enough oxygen throughout their day they will be able to have the energy necessary to deal with the issues they are facing. They don't need Mouth to Mouth to survive they just need a chance to catch their breath.
