Think of fermions like this: your kids are not grown up, and they get to bickering in the back seat when they touch each other (Dad! He's touching me!) You may have a van with three rows of seats that theoretically holds nine kids, but because of the Notouchy Effect (Pauli Exclusion Principle) the kids must each have their own row of seats, so your car can hold no more than three kids, if your kids are fermions.
***One of the experiments which produced the LENR anomalous excess heat effect was by KP Sinha by shining a laser onto the environment and thereby REMOVING energy from the system. Kind of like shining a light into the kids' faces and getting the deer-in-the-headlights response so they sit where you want them to sit.

It's not a good analogy, because the LENR theory you're talking about involves Bose condensates, not fermions. Lowering the temperature is equivalent to lasering off the back two rows of seats. The bosons are then forced to condense into the single seat. The fermions cannot be forced to condense.
