According to the Bible, our purpose, the reason we are here, is for God's glory.  In other words, our purpose is to praise God, worship him, to proclaim his greatness, and to accomplish his will.  This is what glorifies him.  Therefore, in this we find that God has given us a reason for our existence, a meaning for our existence.  We were created by him, according to his desire, and our lives are to be lived for him so that we might accomplish what he has for us to do.  When we trust the one who has made us, who works all things after the counsel of his will, then we are able to live a life of purpose.  How the particulars of that purpose are expressed is up to the individual.
        
             
        
        
        
It is a stimulus because parts of the ear respond to exact stimuli which would make this a stimulus. Our bodies make us able to hear normally but some people's bodies are not able to respond to the stimuli which unfortunately explains deaf people. 
Hope this helps! Would love brainliest if possible:)
        
                    
             
        
        
        
Although heat stroke mainly affects people over age 50, it also takes a toll on healthy young athletes.
Heat stroke often occurs as a progression from milder heat-related illnesses such as heat cramps, heat syncope (fainting), and heat exhaustion. But it can strike even if you have no previous signs of heat injury.
Heat stroke results from prolonged exposure to high temperatures -- usually in combination with dehydration -- which leads to failure of the body's temperature control system. The medical definition of heat stroke is a core body temperature greater than 104 degrees Fahrenheit, with complications involving the central nervous system that occur after exposure to high temperatures.
