Effect of masticating chewing gum on postural stability during upright standing

I think I know why. Since masticating chewing gum is more likely to require conscious processing of the brain, it devolves balancing to the subconscious, which is better adapted to carry out this task. This should be provable by effecting the same delegation (through mastication) for tasks the subconscious brain is more likely adapted to than conscious processing.

Obvious thought: Is it also easier to walk if you're chewing gum (vs. not chewing gum)? Because if so, then a traditional insult might need updating.
