Is there an expression in Japanese that is equivalent to "as far/long as I/you X", for example "as far as I know", "as far as I'm concerned", "as much as you want", "as long as he is still alive" etc? Or perhaps are all those English expressions expressed differently in Japanese?
Some example sentences:
As far as I know, it only takes 15 minutes to travel from Kyoto to Osaka by bullet train.
As far as I'm concerned, that kind of questions is not suitable to be asked here.
Please take as much as you want.
He is working hard to achieve that golden dream of his as long as he is alive.
EDIT: One more expression: "as soon as possible"
