This is accomplished through more effective products, processes, services, technologies, or ideas that are readily available to markets, governments and society.

Chest pain can be caused by anything from muscle pain to a heart attack and should never be ignored. You should call 999 for an ambulance immediately if you develop sudden severe chest pain, particularly if: 1  the pain feels heavy, pressing or tight.  the pain lasts longer than 15 minutes.
This causes pain, nausea and muscle tightness in the chest -- hence the feeling that your heart is heavy, or those sharp pains when you see your crush with someone else. So essentially, your brain sends a message to a nerve. The nerve responds by making your muscles tighten in your chest. It feels like your heart is heavier, or that you're in pain, or both. When you stop being sad, your brain stops sending the message.
