Friction causes heat, heat creates distress, distress makes parts fail, failure costs a lot of money to fix. In humans, distress causes anger, frustration, pain, misery, and all that stuff costs a lot of money to fix too.
Engineers who reduce the stress between parts make a great living. So do marriage therapists and comedians.
My car engine uses oil to reduce the distress (let's just say stress)on very strong parts that break very fast without it. My watch uses oil for exactly the same reason. So does the gadget that my wife and I use to heat milk for our coffee—yes, we have such a gadget and love it when it works. When I'm acting like a cave man, my wife smiles and bats her eyes and like oil, her demeanor reduces stress.
Our brains can supply all the oil we need to reduce stress. Stress is friction, and too much is failure. You can know the areas where the friction is getting too hot and take steps to reduce it.
[Shameless plug: I use a powerful psychometric survey that can identify where the stress is causing friction. Technology + science!]
If we where the stress is, we know where to apply the oil, wouldn't you agree? Less friction smoothes things out and gets you what you want faster.
Perhaps you do not need such a product to oil your hot parts. I completely understand, and do not blame you one bit for resisting. Nevertheless, please don’t ignore that stress is friction, and friction causes heat, and too much heat makes things to fail, and then it costs a dump truck load of money to repair.
