◦ 38.1%
◦ 57.1%
◦ 85.7%
◦ 10.4%
◦ 23.2%

Question 2

Hypertension is a silent killer because it is deadly and has no significant early symptoms.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
