Life is a death sentence, unless someone has unlocked the key to immortality. I'm sure there are people who've lived less years than me who have still lived a fuller life than me. Randy Pausch, of Carnegie Mellon University, comes to mind:

Just because you're born knowing you're going to die doesn't mean we should all fret about it (unless you're a Nihlist of course, and then it doesn't matter as everything is futile). Knowing you're more likely to pass sooner would hopefully be a good thing in that you'd hopefully spend more time with your family creating memories than useless stuff like grinding at work and trying to climb corporate ladders only to become a senior middle manager in 20 years.

Personally, I would absolutely want to know to pivot my life towards reality. I'd much rather have an educated guess as to what my future might hold given the options vs sticking my head in the sand and "hopes and prayers" for the best. That being said, I can understand how it might simply be overwhelming for some people who wish to remain blissfully ignorant. Best of luck to them!
