Can a mathematically sound prediction interval have a negative lower bound?

What do you complain about your life and what no to complain?

• Since I do not know the meaning of life, I will go with the things that are the most basic. A person can not be living on earth if it were not for his or her family,so can not complain there. My family were equally supportive when I was in school and or of school, so can not complain there. I spent most of the holidays by myself. I would know because the stripper at the club actually had asked me did you know today was Thanksgiving. And on that day the public transportation was slow.And when my went to gym, the person who worked at the desk said good birthday to you. It is not a bad thing, again I can not complain. I know I don't watch TV as often as I should, but I do know that two things are bound to happen, picture and sound. I do not have cable, net flix and video game console, yet my TV volume changes on its own. How does it happen? the answer is it should not happen, otherwise there is NO need for the volume controller. So it is obviously someone is doing the dirty work. But why me? ( saving private Ryan) If it were a guy, NO comment. If it were a female, ok two things. If you are under 24, instead of messing with someone's TV volume, please go outside and meet a guy or a girl or both. If you are over 24, maybe thinking about things such as ( you fill in the blank). if you are over 33, maybe time should be better spend with your children? TV volume, are you kidding me? Volume, Volume? what about the constrast ratio? if you think you spend enough time with your children, what about getting an additonal child? if you are too old for that, what about the option to adapot? I am the last person on earth to tell others what to do, but volume changing for a person who does not have cable, video game console and net flix? are you kidding me? So I have to complain a little. Another thing I have to complain a little is my currently living situation. Since I can not stay at outdoor 24 hours a day, I have to come home at some point. And when I do come home, there is no working light, heat, gas, stable tempature running water, internet. So I sit all day. that is sitting as in with a chair. But I can not complain since it was like that from day one, in other word I chose to accept it from the very beginning. I am sure if it happens to me it can happen to anyone. Another very important thing is the things people ( earth population) value in life, not talking about moral standards here. First, I could ONLY speak on myself. And to me, respect, kindness and gernerous all GO after two other things and they are. 1) treat all people the SAME and 2) treat others how you would be treated. I do not make eye contact with anyone, not just you, anyone. Reason is simple, there are x billion amount of people on earth, if I look at you and do not look at the people who live in South Africia. I am treating people differently. And it should not happen. So that covers 1. On the issue of treating people as you would like to be treated, it is actually a lot simpler than it actually looks. For instance, when I do not make eye contacts with others, there is NO way for me to know if they are actually looking at me or not. Therefore, when others refuse to look at me in public does not sound as bad as it is. Other example, people who to go work complain about the commute is bad. Well, I take bus at 2 AM in the morning. There is simply nothing for me to say. Lastly issue, how people turn out the way they are. Ok, there are many variations contrube to this, I will keep it simple. It is 70% parents, maybe given or taken 5% here. Ok here is the thing, once you begin to go into that area, the first thing some people will say is their parents. Then it really,REALLY leads to NO where. There are six types of people in this world, nicest people on earth, nice people, good people, not so good people, bad people and very bad people. (noticed I have excluded the evil people). So the chances are one of every six people, there is bound to be a nice person out there. I know people will tend to disagree, but by assuming all people are evil by default, I do not see the point of living on earth. Assuming you got a good dice roll and had a nicest person on earth as a parent. What happens next? He might have time for you or he may not have time for you. Look at Andy Reid's kid, enough said. Of coure had he spent a fraction of the time he did with T.O on his child.... What I am trying to say is using my parents were bad as an excuse to mistreat your kids is not a solid excuse. Moreover, they could be 1) nicest person on earth and 2) devote all the time into you, after all it is only 1/12 chances and they are x billions amount of population on earth. But the main thing here is I was NOT there, so it is totally your word against my wild prediction. Man I should get cable soon.

• Answer:

  Yep, a lot of people have it worse and I can't expect more from others that I would expect from myself - but I complain anyway. How else can I display my disappointment with the condition of society and my place in it. I know I can't change it, but that ain't a reason to keep silent. I've been accused of being a grouchy opinionated old man - and I guess the metaphorical shoes fit me well. I have to live here, there isn't an alternate world where people are intelligent and use their ability to reason to benefit the greater good, but I don't have to smile and like it. Just as i have to deal with fools but don't have to accept their foolishness.
