Abstract
Many sports skills require quick reaction times: think of hitting a 95-mph fastball, returning a 100-mph tennis serve, or blocking a slapshot at the net in hockey. (The Experimental Procedure section below has one way to measure reaction time.) Is your right hand faster than your left? Can you improve your reaction time with practice? Do both hands improve if you only practice with one hand? Try relating your reaction time to real situations in your favorite sport. For example, calculate where the baseball is on its way to the plate when the batter has to make his decision to swing. In addition to reaction time, it takes between 150–190 milliseconds from initiating the swing to making contact with the ball. You'll also need to know the distance from the pitcher to home plate, and the speed of a pitched ball. (Wiese, 2002, pp. 6–8; Adair, 2002, Chapter 3; Brody, 1987, pp. 145–147.) See the Science Buddies project Think Fast! for a step-by-step procedure.Bibliography

Human Biology & Health.
Doctor's need information to decide if a person is healthy or sick, if a baby's earache is bacterial or viral, or if the man next door needs medication to lower his cholesterol and prevent a heart attack. The information often comes in the form of results from lab tests. Medical and clinical laboratory technicians are the people who perform these routine medical laboratory tests, giving the doctors the information needed to diagnose, treat, and prevent disease.
