Occasional difficulty swallowing [Swallowing is a complex action involving the muscles and nerves within the pharynx and esophagus, a swallowing center in the brain, and nerves that connect the pharynx and esophagus to the swallowing center.], which may occur when you eat too fast or don’t chew your food well enough, usually isn’t cause for concern. But contineus fast eating and not chewing properly, for years, may cause persistent dysphagia in old ages and may indicate a serious medical condition requiring treatment.

To avoid ageing, avoid eating fast and chew better !
