Selective Amnesia and Plumbers Cleavage

The mind is a funny thing. At some points it seems to have infinite capacity and sometimes it is like a water heater.

Like a water heater???? (I'll say it for you - HUH???)

A water heater is just a big bottle with a pipe of water flowing into it and a pipe of water flowing out of it. (There is a heating source of some kind and a heating source shutoff but that isn't important right now)

It is a contant pressure system, at any given time (provided you have paid your water bill) there is the same amount of water in it.

If you turn on the spigot and let hot water out of it, brand new cold water from the city flows into it to be heated up. The old is replaced by the new. Because it has a finite capacity, there is always a mix of old (hot) water and new (cold) water.

Bear with me on this, I had a whole analogy with BB's and a Turkey Baster but I didn't want to be censored for perceived content.

Over time the old is supplanted by the new but a little of the old remains. The more you use the hot water, the more the change.

Okay, this is a messed up analogy.

Memories are like that. Over time people forget much of the old information (or bury it) and it is replaced by the new. Still, a hint of the old remains. If you transitioned at, say, 25 and you are celebrating your 95th birthday, is everyone going to remark on those first 25 years? Probably not, you have filled your life with more experiences and they overshadow the pre-transition information.
