A Deep Thought for the Day

Muscles are affected by how we use them, aren't they? Those who run a lot get more muscular legs, and ballet dancers look very different from the rest of us because they dance so much. So what is the effect of speaking different languages on our tongues? Take the rrrolling triple-r sound. English speakers don't use it at all, but I find it very good exercize for the tongue. Does this mean that I have a more flexible tongue?

This is what happens when I try to write lots of very serious posts.
