I am quite young, my family is still healthy. But I would like to see my great grandpa again, but I wish I saw him when he was younger, he died when I was 7 and I had not known him until he was in his 80's, so he was already "out of it" when I first met him. But my mother talks about him because he was her most favorite person, she talks about how he used to run a pizzeria and very sweet things. I wish I had known him better.
While I haven't lost anyone personal to me, I believe people die when they're supposed to.
And again, I've never lost anyone close to me. So I might feel different in had experienced the loss.
