1. Learn the basics of nonverbal communication.
One study found that nonverbal communication accounted for 55 percent of how an audience perceived a presenter. That means that the majority of what you say is communicated not through words, but through physical cues.
To communicate clearly and confidently, adopt proper posture. Avoid slouching, folding your arms or making yourself appear smaller than you are. Instead, fill up the space you are given, maintain eye contact and (if appropriate) move around the space.
Keep exercising regularly and doing good things to your body then you wont have to worry about dammaging your body
Know which noises can cause damage (those at or above 85 decibels). Wear earplugs or other protective devices when involved in a loud activity (activity-specific earplugs and earmuffs are available at hardware and sporting goods stores). If you can't reduce the noise or protect yourself from it, move away from it.
