Cookability

I mean, good general rule, but this way ppl with various disabilities are less likely to have heavy piles of things to lift in order to get out the thing underneath and fewer things makes it all less cognitively overwhelming and when you move there's fewer things to move and so on.

Also, people with various disabilities tend to have lower incomes, so cultivating the skill to know what is essential and what isn't is also useful. I am, as we speak, beginning a process of sifting through my not-extensive possessions and part of that is so my ADD brain isn't overwhelmed by stuff - since I don't expect to live in anything besides small rented apartments for years to come.
