That sounds like something you'd need to upkeep, with some downside if you miss it. Immortality that just "works" should be impossible/really hard. I'm thinking of a grove of peaches where if you eat one every week you don't age, but if you miss your dose you take aging penalties until you have another, even though you're still technically not old. Something something the time that would have passed weighs you down or something, lasting until your next dose or until all the time has passed that you stopped.

I don't think immortality should be all that rare or hard to get, but immortality where "No one knows how she's still alive" happens should be "basically" impossible. The other types should be rather obvious, oh this person bathes in the blood of the innocent. This person is an undead and stopped his heart and is as cold as the grave now. This person has to take a drug once a week, every week, till the end of time. This person has to take care of a sacred oasis and so long as it's healthy and the waters clean it literally washes away old age. Be a real dick move if someone poured poison in it, a reaaaal dick move.
