If vegetables are healthy for us, why don’t many people like them? Shouldn’t our body crave the nutrients?
In evolutionary terms, vegetable items are available in great abundance, but salts, sugars, fats and proteins are far more difficult to obtain. Fast forward to today in the developed world, our bodies are still programmed to seek out these foods and assume that we will get plenty on vitamins ,minerals and fiber from our environment.

Do snipers have to do math and what are the physics involved in shooting?
Snipers have to do a lot of math. They have to calculate the distance to their target, and how far the bullet will drop over that distance. They also have to account for drift imparted by the wind and the effects of things like temperature, air pressure, and humidity. At long enough range they may even have to account for the Coriolis Effect caused by the spinning of the Earth.

How does a computer turn binary into complex programs like PC games?
If I give you a list of numbers, it would be pretty meaningless.
But if I start to give meaning to some of those numbers, clever things can happen.
The first page of numbers will always be a list of instructions. I will have to explain to you what each number means. One number might instruct you to add two things together. A different number might instruct you to move a piece of information around. Yet another number will tell you to access some external hardware (a pen, some paper, another person, maybe even someone who’s playing the computer game). The computer knows what these numbers mean because they’ve been built into the very hardware of the central processing unit when it was designed and built.
On the next page, the numbers represent pictures used in the game. Some of the instructions on the first page tell you when to use each picture. Other instructions tell you how to use the numbers to make a picture – that each group of numbers represents a pixel on the screen, and that within each group, there is information about how much red, how much green and how much blue to display in that pixel. Other images need to be generated automatically by following instructions to draw lines or draw circles (or more complex things) depending where the objects in the game are.
The next page consists of sounds. Each number represents a point on the sound wave, and tells the computer the amplitude of the sound wave at that point. These numbers can be passed directly to the sound system, so that it can make the right sounds, and the instructions on the first page will tell it when to do that.
Obviously it’s a lot more complex than this, and would take pages many books to explain thoroughly.

If stalking is a crime,why are paparazzi tolerated?
I’m going to quote the California stalking statute. Other states and countries will be different but this is an example.
(a) Any person who willfully, maliciously, and repeatedly follows or willfully and maliciously harasses another person and who makes a credible threat with the intent to place that person in reasonable fear for his or her safety, or the safety of his or her immediate family is guilty of the crime of stalking, punishable by imprisonment in a county jail for not more than one year, or by a fine of not more than one thousand dollars ($1,000), or by both that fine and imprisonment, or by imprisonment in the state prison.
The emphasis is mine. In order to be guilty of stalking you have to make the person afraid for their safety. Paparazzi might be annoying but most people aren’t worried for their safety around them.

What makes a Race car driver “good” at racing?
Top tier race driver needs to have great mix of skills that include
1. driving skill – being smooth with the car, knowing the limits, being able to feel the car, to sense the optimum line, react instantly to the unexpected. The smoothness is the reason why fast drivers look like they are driving slowly, but it is needed to maximize traction, thus speed.
2. Balance of aggressiveness and cool headedness. The driver needs to be aggressive enough to eg. commit for overtaking manoeuvres, resist other drivers’ pressure, but at the same time, “to finish first, first you need to finish”.
3. technical competence. They say that the edge Michael Schumacher had over his competitors in his golden days was that he understood the car well and could help with proper set-up. For not the jet-setter levels of drivers it is even more important, they often need to help with the car themselves
(4. Sponsors and networking. To break into the top level of drivers (ie. F1, GT2 etc.) you need to have serious money behind you.
5. physical fitness and low weight. Lot of the events are physically demanding, require several hours of exercise and concentration. In some of the disciplines the driver’s weight is substantial part of the total vehicle weight. having 10kg less can mean 10ths of a second on a lap)

How do free apps with no ads (snapchat, instagram) make money?
Imagine your parents gave you $50 for the latest video game. There are other kids selling sub-par lemonade, old video games, comics and orange juice on the block for various prices from $0.05-$0.25 a cup. A days labor earns them anywhere from nothing to a few bucks. And you see these kids with their mud-pies and urinade, and you think to yourself, “I could totally do better.”
You decide to put your $50 into a lemonade stand instead of a video game. Hell, you even innovate and add sugar to your lemonade (crazzzzzzzzzzy). Now, you can competitively price your lemonade or advertise Johnny mud-pie for a small portion of his daily $0.50 profits, but that’ll just detract people from what you’re offering. Plus, they might find it mildly annoying.
No, you have bigger plans than that. You’re not running a mom-and-pop lemonade stand, you’re going platinum. But nobody knows you, everybody knows Johnny mud-pie and Orange Juice Simpson. How do you bring people to the table? light bulb You spent $5 getting this lemonade stand started, why not use the remaining $45 for a year of operational costs and give your lemonade out for free.
At a price of nothing, your lemonade quickly becomes the rave. All the other kids have already blown their profits and can’t sustain their business models, not when the competition is offering a product for free! Everybody’s coming to you. Who would pay $0.20 for pee, besides Pedophile Peter, when they can get your awesome lemonade for nothing?
Over the course of a year, you’ve built up a popular customer base. You’ve innovated a bit more, your lemonade now has caffeine in it, and all the local grown-ups stop by your stand instead of going to one of the 30 local Starbucks. Not to mention, everybody that passes through your neighborhood pulls over. Some people even offer a donation, but you lower your shades, give them a half smile, and in the deepest voice you can muster, tell em, “It’s on the house bud.” It’s time.
Johnny mud-pies has moved a few blocks away. His mom caught his dad with somebody in their room. IN THEIR ROOM. They’re going through a divorce and Johnny spends half his time on the other side of town. He’s richer now though, Johnny. He’s got money coming in from two separated neglectful parents instead of one neglectful couple. His allowance has tripled as his parents try to buy their way to his teeny little heart. He’s thinking of getting back into the game. He’s found a new source for mud. But he needs your help. He’s seen your business acumen, the way you drove him out of business with a product that wasn’t even in the same category.
Johnny offers to buy some space on your lemonade stand to market his product. A year ago, you would’ve said hell no. Your customers would’ve said hell no. Hell, you wouldn’t grow so quick as new customers would’ve been put-off. But now you got a steady stream of lemonade junkies. They ain’t goin nowhere. Word gets around that Johnny mud-pies is raking in made cash. All of a sudden, several new and old business are popping up around the cul-de-sac and around the block. You started with 50 bucks, you grinded on that chump change for a minute, and now you can’t even count the money you’re making.

Why Japan’s population is in such decline and no one wants to reproduce children
When you give people a choice between having nice things and a lot of freedom and independence, or having children, it turns out that the women chose the nice things and the independence.
Japan has a culture where women, once married, are expected to give up careers and focus on family, and that includes focusing on the parents of their husband, and their own parents if they are an only child or there is no son in their family. The pressure to conform is intense.
All across the OECD (the Organization for Economic Co-Operation and Development, a club for rich countries), birth rates for “natives” and 3rd+ generation immigrants are just at or often below the replacement rate. If it wasn’t for net immigration in from places with higher birthrates (Southeast Asia, the Middle East, Africa, Central & South America) most OECD nations would look like Japan in terms of population graphs.
The Japanese people are xenophobic. They don’t want foreigners to become permanent residents and the older people are the more xenophobic they are. Laws on long term residency and becoming naturalized Japanese citizens are very strict. So they are not going to do what the other OECD nations are doing and increase the inflow of immigrants to offset declining “native” birthrates.
One could speculate that the hypersexualized, extremely abusive cultural aspects of Japan (where rape fantasies, lolita fantasies and abuse fantasies are “mainstream” content consumed by millions of men) doesn’t do much to incentivize women to be interested in sex either. If the men are programmed to find fetishistic behavior degrading to women “sexy” and I were a woman, I would likely find most of my potential mates interests in the bedroom quite distasteful.
