Be Intelligent, Be Fit?

As I sat in a wooden chair in a certain room, I was given a task that shall utilize my not-so-great writing skills:

to compare and contrast an athletically-inclined person and an academically-inclined person, and choose between them if ever the chance to change comes.

Wow, I think my other skills (thinking and the likes) won't work as effectively as before with this kind of task, especially with the choice-making.

Okay, let's cut to the chase.

To start the comparison, we have a definite for both persons, that being their inclination is to only one aspect. The athletically-inclined person, as implied by the adjective, is basically a brawny person. Physically fit. The academically-inclined person, on the other hand, is a brainy person. 

The brawny person is most likely a very physically active person, which is a useful trait to have in situations requiring physical strength. They are also most likely to have a strong immune system, great amount of stamina, and would probably live longer than a brainy person. However, the brawny person may have drawbacks when it comes to mental ability. The brainy person, conversely, comes back with mostly mental abilities. They are most likely to have a great memory, critical thinking ability, and great logic. Likewise, they may have drawbacks but this time it's in terms of physical ability.

Now, who would I choose? Let's remember now that each person is only inclined to a certain aspect, not entirely locked to one. I'd choose to be the brawny person if ever the time comes, because I'll first have to consider my survival as an individual. The learning can come later. Now, why not be a brainy person and be like "becoming healthy can come later"? Firstly, it's because my number one priority is survival. It's anyone's priority. To look at another point of view, brawny people can learn as anyone can learn, but brainy people can rarely be of the same physique as a brawny person. 

It's quite vexing to think of, but it's my final opinion. I say final because I did lots of thinking here because both is almost in the same rank with one another. I just chose being brawny because I choose life first. Another reason is brainy people are usually serious because they can think of life very thoroughly, and people with serious outlooks on life usually are very sad people. I choose not to become sad again if ever I repeat my life and choose between these two types of persons. 

Brawny or brainy?

My judgment has been brought down. What's yours?
