Anthem has a pretty decent plan (at least in Indiana). The Indiana University system has good insurance for grad students, with no co-pay when you use the student health center. UGA was the same way.
I love tall women who wear heels. It's so glamazon. I'm 5'2 or 5'3 so I will never get to experience this! I definately don't think 4" is too much. That's a fairly standard stilletto height. I know a lot of professional women who wear 4"+, since obviously it's a trend in footwear for the past season or two to have towering heels and big platforms. That said, for a conservative law firm, I probably wouldn't go over 4", but I think this is a perfectly appropriate height.
