I work in software in the auto industry and as such there is a concept of a core. This is not what most people think of when they refer to their core being, but having read midlifecrisis50's thread, it made me start to think.
In auto parts a core is the empty shell left over when some or all the parts that can wear out do wear out. In a Battery it's the plates or terminals or corrosion causing issues , in an alternator it's the brushes, bearing/bushings/terminals. When you remove all the replaceable parts, all that is left is a shell that can be rebuilt. If the shell is cracked, it can't be rebuilt. If the wrong new parts are put in the shell, it either will work poorly or won't work at all. If a wrong part is put in and it doesn't work, you can usually remove the wrong part and put in a new one that does work, unless the part you put in destroys the shell.
Do you see where I'm going with this?
The part that always confused me is the absolute NEED to get away. The anger and horrible things an MLCer could do to someone makes sense if they believe that person is keeping them from escaping or getting what they need and they feel they must escape or die. But what causes that need? WHAT IF that person has simply used up all their brushes or bearings? We all know we have individual limits, capabilities and experiences that shape how we handle things.
Everytime a person has to face a major event, they use up some extra of their brushes or bearings (good or bad). Maybe some people have something stuck in their bearings that make them wear out a little bit faster. Maybe some people know how to replace their brushes and bearings on a regular basis (sharpen the saw or recharge the batteries) and some people don't recognize that need. But bottom line, what if someone just wears out their brushes and bearings, all the worn out parts fall out and all they are left with is a core, an empty shell. They know they need to fill up that shell with something, but the people around them want to put the broken bits back in. The MLCer knows that is no good, but no one else can understand it. So they must set out to find new parts away from people who want to put the worn out parts back in. They HAVE to go, or they can no longer function.
During the course of this journey, they add parts that aren't right for their core and if they add too many not right parts they have to figure out which ones are the problem and which ones work. This can be time consuming because maybe some of the parts kind of work and some don't at all, but a different combination has the same effect. (in this case I'm thinking engine: a bad spark plug behaves the same as a bad wire behaves the same as a bad ignition coil. If all three are bad or 2 of three on the same cylinder, it's the same behavior). Even if everything seems to be running OK, if they have the wrong parts it will eventually catch up (you can use a 12v battery in a 6v motor and it will run for a short time, but it will burn out the motor)
This would mean the end of MLC would be if all the parts were replaced with correct parts (which might run considerably better because OEM is not always as good as some replacements) and the MLCer had not cracked or harmed their core. Or if they kept replacing with wrong parts or substandard parts, they could not get to the finished product. Or if they cracked or harmed their core, they would never get to a finished product.
For me, if I look at it that way, it starts to make more sense. That someone wore out their brushes and bearings, didn't see it coming so could not do preventative maintenance, and there they were, just a shell they knew they needed to fill up to get going but not able to put words to it.
