If your beans are taking forever to cook, are you adding salt? Adding salt will keep beans hard -- wait to add it until the beans are fully cooked.
Also, I second the suggestion to either make your fridge colder, or replace it.
the fridge isn't mine -- came with the apartment. and it's a communist era fridge (complete with Russian labeled dials), so it probably dates back to before the wall came down. i have it on medium setting and will look at acquiring a thermoter to see if that means <5°C like it should or, something ridiculous like 10°C (i think i'd notice if it was warmer than that. it feels cold to me.)
I think the beans in question are just old beans. I add salt to taste at the end.
An exercise:
Name something that you do not do but should/wish you did/are told you ought, or that you do less than is normally recommended. (For instance, "exercise" or "eat vegetables".)
Make an exhaustive list of your sufficient conditions for avoiding this thing. (If you suspect that your list may be non-exhaustive, mention that in your comment.)
Precommit that: If someone comes up with a way to do the thing which doesn't have any of your listed problems, you will at least try it. It counts if you come up with this response yourself upon making your list.
(Based on: Is That Your True Rejection?)
Edit to add: Kindly stick to the spirit of the exercise; if you have no advice in line with the exercise, this is not the place to offer it. Do not drift into confrontational or abusive demands that people adjust their restrictions to suit your cached suggestion, and do not offer unsolicited other-optimizing.
