People who are physically active throughout their lives may add about year(s) to their life expectancy.
The answer is letter b. 1.5. Here are the explanation.
As for older people, the study estimates that if they are active at age 80, males and females will get a lifespan boost of 1.2 and 1.6 years respectively. Hispanics tended to benefit little from physical activity in terms of life expectancy, although this may be because the surveys were not well structured to ask questions specific to their culture,
The results are also minimal, as something other than exercise — such as a balanced diet — could have improved life expectancy among those who have lived longer. However, the researchers have attempted to account for that.
National Institutes of Health Science that studies physical activity, said a study released showed that as little as 15 minutes of exercise a day would make a difference in terms of longer life span.
