Hajime no ippo started started in the late 1980s(800+ chapters) and as far as I know it's still being done by the same Mangaka. Though I can't find much information about him so I have no idea how old or near-death he is.
Well it happened to the creator of Trinity Blood, he died and his friend took over in order to write an ending to the series. Ever wonder why Trinity Blood's ending didn't really end the Anime, it's because the Novels could not be completed.
I would like go emo for like an hour after hearing/reading the news...then go re-read chapters or re-watch the series' anime. I'd probably then go and find a new manga to read, or just go and focus on the other manga I read.
