Short idea (47): Some experiences are too painful to remember. This doesn't mean they're gone.
The first snow covers the grass.
Soon we forget the grass.
But it's still there.
Short idea (59): If you have a camera whose pictures are getting more and more inaccurate — this is a good metaphor for getting old. Decaying tools can cause problems. There are additional problems if you don't know your tools are decaying. And still more problems when you insist to others that everything's fine when everyone can see it isn't.
Short idea (95): Every experience has a "tail," which is to say that a piece of every experience lingers on after the experience is over. For example, the experience of being in a severe thunder storm lingers after the storm is gone. The alertness, the feelings of fear and/or awe, etc. Tails can last a few seconds, a few minutes, a few hours, days, weeks, months, years, and even for a whole life-time. As you get older you accumulate more and more of these permanent tails, and all new experiences you have are filtered through them. The thicker the web of old tails, the less of each new experience will get through, and, gradually, new experiences will all come to feel pretty much the same, have the same flavor, as it were. Experience will become stale.
Longer observation (12): A Suggested Model of Memory: Here I would like to make a suggestion for a possible research approach to Memory.
Short idea (161): Memory is a skill.
