asked: "You inspired me to create my own Sailor Moon blog! usagiofthemoon! Also, do they ever explain why they live so long in the future? I've read the whole manga, and watched the anime, but I don't remember there being any kind of explanations."
Aww that’s so sweet! I can’t believe I actually inspired someone!
Everyone can live so long in the future because the Silver Crystal gives them that ability. I know that the manga states this, but I’m not sure about the anime.
