I can think of two general scenarios where having a nice big spleen would be advantageous. One is in the performance enhancement context. Your runner, maybe there's a way, I'm not suggesting this as a protocol that you know like getting your face into some cold water, holding your breath could afford you a kind of a boost. So instead of the scuba tank boost underwater, you're getting the above ground boost in endurance or strength output.
