Are short people better than tall people?

Yes, Here is why:

Physical advantages of shorter height
Shorter people of the same proportions as taller people have many physical advantages based on the laws of physics, and these advantages are supported by many researchers. Shorter people have faster reaction times, greater ability to accelerate body movements, stronger muscles in proportion to body weight, greater endurance, and the ability to rotate the body faster. They are also less likely to break bones in falling. As a consequence of these physical attributes, shorter people can excel as gymnasts, divers, skiers, martial artists, rock climbers, figure skaters, rodeo riders, soccer players and long distance runners. Within their weight classes they are excellent wrestlers, boxers, and weight lifters.
Shorter people are also less likely to require surgery for herniated spinal disks. In addition, shorter people are less likely to break a hip from falling. Another advantage of smaller people is that they are less likely to die in auto crashes. One study found that people weighing less than 132 pounds had the lowest risk of dying or suffering serious injuries compared to bigger people. Although height data weren't provided, it is known that height and weight tend to be correlated. Thus, lighter weight people are more likely to be shorter than heavier people. No adjustments for air bag deployment were made, although other studies have found them to negatively affect short people.
