That reminds me of the one about how President Carter brought a pooper-scooper to the Strategic Arms Limitation Talks...
Unless by 'look after themselves' you mean you don't find them physically attractive and think you deserve a 8/10 or better
My exact words were "take care of themselves" and yes, that's what I meant... but the issue is why:
When people (regardless of gender) respect themselves enough to take responsibility for their decisions (particularly where those decisions pertain to health, diet, hygiene, exercise, etc), it's impressive, and those people aren't just likely to be more physically attractive (i.e. "superficially"), they're likely to be more attractive period (i.e. psychologically, emotionally, hell biologically).
