I said you don't see "conventionally fit" guys. You inferred my claim was that physical fitness was not required.

And the reason I used bowling is because it is a physical sport. And with physical sports, better overall physical fitness can give you an edge.

Hell, even in chess they're beginning to consider how physical conditioning impacts performance.

But now you're kind of at the point of arguing the metaphor. There are more desirable positions in software development and less desirable ones. And everyone is applying for everything. And if one group is cut off from the more desirable ones, they will start to become over-represented in the less desirable ones.
