I think it relates to mirror neurons.
Whether you can grow and wire additional mirror neurons, as if you could grow another arm or leg, I'm sceptical of. The next best thing being able to wire the neurons that you currently have, being aware on some level.
I think someone like Richard Branson might have more mirror neurons than usual. Making better negotiators and better able to serve people's taste in music & culture, for example. It may also make you a better learner from people.
