"   Anmar Mirza Williams, Ind. Years on Job: 23     There are nearly 15,000 caves in the central United States, and an estimated 4000 people who explore them each year. Anmar Mirza, who volunteers as coordinator for the National Cave Rescue Commission&amp;#039;s central region, makes sure they come out alive. The 38-year-old has performed 80 rescues since 1985, embarking on blind searches to locate lost or trapped cavers. When he&amp;#039;s not running a company that sells caving equipment, Mirza trains fellow rescuers to operate in tight spaces and total darkness. &amp;quot;It&amp;#039;s not about being brave,&amp;quot; he says. &amp;quot;It&amp;#039;s about being prepared.&amp;quot; "^^<http://www.w3.org/2001/XMLSchema#string>
