No one is the person they were in the past, Hinata. Were this a movie, or some kind of written medium, that would be called character development.

Not often- more than prior, I suppose. There were periods of time where I did not require sleep for months at a time.

Things are different now. Character development. If need be, however, I can still function without it for multiple days.
