physical fitness is better than mental fitness

Exercise(the prime requirement for good physical health) stimulates the release of neurotransmitters called endorphins; this release makes people happy and helps people to be alert and mentally active. [[http://health.howstuffworks.com/mental-health/human-nature/happiness/exercise-happiness2.htm]]

Tall people are not stupid! [[http://www.conanstevens.com/tall-actors-giant-life/conan-stevens-life/big-tall-people-are-not-stupid—and-my-mensa-membership-genius.html]]

There is a significant positive correlation between height and intelligence.-[[http://en.wikipedia.org/wiki/Height_and_intelligence]]
The fitter you are as a growing child the taller and smarter you are, in comparison to students of the same age.

“Studies show attractive students get more attention and higher evaluations from their teachers, good-looking patients get more personalized care from their doctors, and handsome criminals receive lighter sentences than less attractive convicts…The ugly truth, according to economics professors Daniel Hamermesh of the University of Texas and Jeff Biddle of Michigan State University, is that plain people earn 5 to 10 percent less than people of average looks, who in turn earn 3 to 8 percent less than those deemed good-looking”

Yes the world is highly look-ist and studying all night for an exam will probably not help you score as well as getting a good night’s beauty sleep before the big day and looking prim for the exam will. [[http://kidshealth.org/teen/your_body/take_care/how_much_sleep.html]]

Healthy sleep habits, healthy eating habits and good health as a whole contributes more than intelligence to success and joy.

Counterargument:
Good-looking convicts are all physically fit.

The connection between fitness and Endorphin has already been highlighted in the first point.
Fit people are also happy because they are more likely to dance all night at parties or nightclubs; since some clubs do not permit overweight people to come in.

In our zeitgeist facial features and skin colour no longer dictate what/who is attractive and all criteria for good looks boils down to friendly facial expressions,good posture, fit bodies, good skin, clothes and hair. Anyone who is physically fit qualifies. [[http://www.beauty-fitness-guide.com/]]

Often these conditions do not cause the physical unfitness, but instead are caused by the same factors that caused the mental disorder. For example, people who do not feel empowered often have mental health disorders. People who feel like they lack empowerment also do not visit the doctors. They do not feel that going to the doctors will help. There are other factors that we need to assess rather than just linking the mental disorder to the physical disorder. For instance, the medication that people take often has a large impact on physical health[[http://www.rethink.org/how_we_can_help/news_and_media/briefing_notes/briefing_5.html]]. We therefore should not just assume that it is the mental illness itself that causes the physical unhealthiness.

But in order to achieve your mental goals, using your example for research or programming, you need your physical health in order to conduct the research as effectively as you can and for as long as you can. A researcher crouched over his desk and not exercising or seeing sunlight will not be physically healthy and therefore he will die sooner [[http://www.dailymail.co.uk/health/article-1309650/Mens-health-No-exercise-long-hours-double-fatal-heart-risk.html]]. If they only spent the recommended half an hour a day doing moderate exercise they could have achieved far more.
