There's is sort of a natural efficiency in forgetting some things.

Sort of a sieve of things that weren't worth doing anyways.

[falcolas]

It's less useful that the things most often set aside are the most mundane but required parts of life.

For example: brushing your teeth. Showering. Getting prescriptions. Scheduling and following through with doctor's appointments. Paying bills (thank the gods for autopay). House repairs. Calling someone to do house repairs. Going to meetings at work. Remembering to leave for work on time. Remembering your wallet.

And so forth.
