Quizplus · Accepted Answer

All three statements are true. Research has shown that left-handed individuals are more accident-prone due to living in a right-handed world, as tools and objects are designed for right-handed use. Left-handed locomotive engineers may also experience higher accident rates as a result of controls being designed for the right hand. Finally, in the past, children were often forced to switch from left-handedness to right-handedness, and as a result, there may be a lower proportion of very old lefties as they may have learned to masquerade as right-handed.
