You can't just always only look at the positive things, you have to be aware of the negative things as well. Such a viewpoint is very susceptible to crumbling as soon as things start to take a turn for the worse. Chris Hadfield talks about this in his book about becoming an astronaut; he intentionally thinks of all of the worst things that can possibly go wrong, and then comes up with a solution for each and every one. That way, if things ever do start going wrong, you can still be confident in your ability to resolve the issue. | ||

I use this way of thinking too, but also so that when things do NOT go wrong, I explicitly notice it, and I am happy about it. An other way of putting it is that my 'normality' is not [normal is fairly good and everything worse is bad], but I consider everything fairly bad as 'normal' so that better means good. if you can get my point. Sound quite stupid because too simple, but it is actually quite efficient, and not necessarily easy to apply. The idea is that we are not sensible to "happiness", but to 'gradients of happiness', we need reference points. | ||

Is it cool to drive at night with your high beams on if oncoming traffic is 50 yards to the left? 100 yards? How about being behind someone? I just finished driving across the Canadian prairies and never quite knew, I just kinda winged it. | ||

Or are you saying you are kind of driving offroad with people driving at random spots of the landscape? I really only know how to handle it on roads, and in that case you turn it off as soon as you see someone ahead of you, because otherwise it will blind them. | ||

That being said the only time I really would use high beams is driving country roads at night, looking for deer eyes in the brush off of the road. Not sure where you're from, but the necessity of high beams can differ drastically between countries. Living in NL I hardly ever needed to use highs, but here in Brazil roads are bad, and really DARK at night. Using highs can give you that slightly longer warning time that allows you to brake for an unannounced speed bump, a pothole, or any one of another 100 potential hazards (including people and animals). Don't have to be out far in the countryside on a small road either. That said, most Brazilians drive like utter dicks and leave both their high beams and their mist lights on regardless of who is around, which makes night drives quite miserable :p | ||

Is it cool to drive at night with your high beams on if oncoming traffic is 50 yards to the left? 100 yards? How about being behind someone? I just finished driving across the Canadian prairies and never quite knew, I just kinda winged it. Generally, a highway with significant division it's ok to keep highbeams on. I'd be less willing on a prairie than on hills though (since the different sides are usually on different levels in the hills). If someone is ahead of you generally keep high beams off at most distances. At very long distance on flat terrain could be ok if the illuminated bit of road stops before the other car. The principle is always being able to see all the way ahead of you, except briefly when another car is passing in opposing lane on non-divided highways. Of course, you have to slow down doing that so you can still see your full stopping distance. Had a friend driving in a rural, hilly place at night, he turned off the highbeams for an incoming car and didn't slow enough to see fully and hit a black cow just chilling on the highway. Totaled the car. Cow apparently got back up and ate some grass for at least a bit. Got full payment for value of car from insurance company b/c it's the fault of the livestock owner for letting it get loose. | ||

We know there are viruses that change so fast that it is imposible to make a vaccine for them right now, like aids. This mutations, can change how the virus works. So my question is: Is it posible for virus like the HIV to mutate sso they be able to transmit themselve trough air like the flu? Because we would be fucked if that happened. | ||

Fun fact pursuant to your question, if you can trace your lineage to Europe during the plague, you may lack the CD4 receptor, which the aids virus needs to become active in your system. | ||

Because we would be fucked if that happened. Not really my area, but as I understand, we don't have to worry much about that. Reason is that to spread airborne, the virus kindof have to live in the lungs or somewhere that can be shoot out in the air (like a cold that makes you sneeze etc). HIV lives mainly in the immune system, which is not normally being shot out in the air (well, unless if you... you know... out in the air...). So the HIV would have to change itself quite substantially to start living in other cells of the human body, and at that point they wouldn't be living in the immune cells any longer, and I guess they'd be little more than a cold. But I'm pretty much talking out of my ass here, so please someone more knowledgeable let us know if I got it right or not. | ||

Another fun fact: there are airborne cancers. Only for genetically identical mice though, so us non-identical humans probably don't need to worry. But if we start cloning ourselves too much...!  | ||

I'm pretty sure you are thinking of CCR5, a co-receptor to CD4 and that it is only homozygotes of the defective CCR5 who are so lucky as to be immune to the HIV-1 strain (they can still contract the HIV-2 strain). The explanation for why HIV hasn't gone airborne was largely correct. | ||

He says this is Canadian tradition and when guests come over they can pick a slab of meat they like. It's also handy if you want a snack. Just pick a slab of meat sitting by your chair and yum yum. I'm not sure if he's trolling or not. I'm not to judge another culture's traditions. It doesn't seem hygienic to me. Is this guy telling the truth? Is this actually Canadian tradition? He lives in an igloo. Water runs it. He has a computer. What. He says he pays a guy to shoot electricity into the water that runs the electronics in his house. Igloos. He lives in an igloo. His family built it. It takes a very long time to build these igloos. Completely not true, Canadians don't have running water in their igloos. | ||
