Is there such a thing as a longevity diet? Increasingly, studies suggest the answer is yes.
Around the world, certain groups of people enjoy exceptionally long lives. Consider the lucky people of Okinawa. These Pacific Islanders have an average life expectancy of more than 81 years, compared to 78 in the United States and a worldwide average of just 67.

Often, people with severe hearing loss withdraw socially, because they're embarrassed to ask family and friends to repeat themselves over and over again. People with hearing loss also withdraw because they're afraid they'll misunderstand the conversation and answer with wrong or embarrassing comments.
Degrees of Hearing Impairment
Your health care provider may order a formal hearing test also known as an audiogram. Doctors determine the degree of hearing loss by looking at the range of decibels (dB) -- a measure of sound intensity -- you can hear. People with perfect hearing can hear sounds of all different intensities. People with severe hearing loss can pick up only very loud sounds.
Normal hearing is considered to be in the range of 0 to 25 dB, which is the softest intensity where sound is heard. People with normal hearing are able to make out sounds as faint as human breathing, which measures about 10 dB. Mild hearing loss is in the range of 26 to 40 dB, and moderate hearing loss ranges from 41 to 55 dB. Severe hearing loss is considered to be in the range of 71 – 90 dB. People with severe hearing loss have trouble hearing speech, although they can make out loud sounds, like a truck that backfires or an airplane taking off.
