What joy do you impart by posing a most appropriate question! Yes, what about "life requirements?" Therein lies the problem! For, life requirement - or what I would call expectations - are the sinus through which our anticipations flow. And the failure to meet our expectations - and they are usually far beyond our life requirement - is the cause of our greatest disappointments. So you see the difficulty we are having in defining "life requirements." Yes, of course, scaling down our expectation might make us more accessable and will limit us to what you call "suitable attributes." But, unfortunately, what you might call suitable, might not be suitable for the bearer. Yes, I'm sorry, that's the best I can do. But if you want to read more, like for example about "compatability", click "kpopp" (blue) below and check the website.
