An example with decaying memories

[jkomoros]

Where every so often you fetch a few memories at random, and if they are older than some amount, you summarize them, dropping 50% of fidelity, and then resaving, overwriting the original.

And when you retrieve a memory you re-up it. The amount of decay should be how long since it was last accessed, and how distinctive it is.
