It seems part of the creative side was affected, where you take things on the fly
Yeah. It is part of the cerebellum that supposedly handles automated processes, but lots of things can be affected. It is about an inch-long piece in there that is dead. I wonder now that if I was given the chance to increase the size of a body part by an inch, where I would put it ;D
There is still chance that it improves a bit, but it is getting more unlikely. However, there is the compensation side of things to consider and that is always changing.
