Kind of a longshot but has anyone heard of a Gemorah or any text which mentions the following:
... he wondered why there were old Jews in Bavel, the verse says in order you shall lengthen your days on "the land"... the land refers to eretz yisrael. So how can babylonian jews grow old. He then heard that it was because they get up early and go to bed late in order to learn.
Please let me know where this is. I want to see it for myself.
