hence my earlier comment. you have a serious lack of interests.
..... but, to answer your question, I'd rather know. My mom was diagnosed with cancer recently. At the time they were still waiting for results and I had multiple exams in a week or two. My sister had been talking to my mother and apparently didn't want her to tell me, (I understood what her intentions were, so I'm fine with that) but she told me anyways, I thanked her for telling me, and so at that time we were waiting for results and we would wait and see. I then texted her the night before my exams asking her what the results were (she had her meeting that day with the doctors) and my mom said that she would talk to me after I finished everything, and told me not to worry. I responded to her by texting that that basically amounted to telling me that the news was bad otherwise she'd have simply said so, but that I'd talk to her later.
I then went on with my life and did my exams, and yes, in the first 5-10 minutes of exam taking I did think of it, but then you get into a groove and you do your damn exams. I havn't gotten results back yet, but I'm fairly confident I did well. Life is going to fuck you whether you want to know about it or not, whether you want to live in a few more days of ignorance or not, it's gonna keep fucking you, and it's gonna hurt. I understand not wanting to know, to focus on this or that, I get the rationale, but I just don't subscribe to that. If life is going to side-track you, distract you, whatever, you'll never get to where you want to go regardless. There's only more busy and less busy in life, but there's always busy, everything else is you guaranteeing unhappiness. Deal with it head on and learn to juggle, otherwise go wallow online everyday and deal with the inevitable neurosis.
... but that's just my opinion. I get the other side too, and maybe I'm wrong and I'll end up deeply unhappy with how I've lived my life. I doubt that, highly, but it is a possibility.
