I really think context is important here. I mean, suddenly would suck unless it was, like, a meteor strike or something, where you're just a pancake in the most awesome way possible. But knowing when it would be? That's a double-edged sword.
If it's tomorrow, that's horrible. You have no time to get affairs in order or mentally brace for the fact. Acceptance is the key, and it's not going to happen literally overnight.
Alternatively, it could be in fifty years. That'd be great. Do all the things you're afraid to do, because the worst is far away and set in stone. Have a long and happy life and die with no regrets.
Given the above two, the question falls, to those here who want to answer: Would you know, if you could?
