  1. Do you find that you are not able to think or analyze things clearly when you are outside, (i.e. Not at home), you are only able to focus on the environment and the problems you see with your eyes and make your direct or natural response to it by your sense, not by your brain? Why am I asking this question? I find that I am not able to think deeply or clearly when I am outside. For example, a salesman in a street stall talked to me and wanted me to join or subscribe to their mobile or cellular data plan. I had hard time understanding what he said, it wasn't language barrier at all, it was because I wasn't able to think clearly at all if it was a real deal or any hidden charges when I am not at home (BUT in fact, it's not rocket science). I had to write down what he said and brought it back home, sitting on the sofa, then I was able to think very clearly. Another example is, if I don't write down what to do on a paper or put it in my mobile phone before I go out, I will have hard time recalling what to do when I have gone out. However, it only limits to minor things like buying a new towel, buying a pack of cola, picking up mails in the nearby post office. One time, I had to do a number of minor things like what I have mentioned, I didn't put it into a paper, then when I was outside, I wasn't able to recall at all what to do, then I had to go back home, feeling relaxed, and then I could recall, Oh yea, buying a bag of table salt, a pack of dry cells, and a USB cable for charging (ALL minor things.) It looks like my brain has shut down partly or totally when I am outside, or at least, hard to run it. Is it abnormal? Or common to most healthy adults? Is it a sign of getting old? In fact, I am 30+ and not physically active.
  2. Over the last few decades we have breakthrough in communications, from the time that we can only call by landline and hear only sound from another side to now that we are carrying a mini computer around (e.g. smartphone) that we can do many things with it. However, it looks like that there isn't any breakthrough in medicine (If I am not wrong). Yes, there may be better technologies, better methods, better analysis and understanding of a patient and a disease but it looks like the root of problem cannot be solved, for example, if one has diabetes, he cannot be cured totally but has to manage for a life time, if one is found cancer at its advanced stage there is little thing a doctor can do to change or wish for miracles. Do you agree?
  3. If, to put it simply, avoiding sugars, how about salt? Is it another thing that should be avoided in order to achieve better health?
  4. I truly understand that there is no one answer to this question because ingredients for different brands may vary a lot. but I mean, on average, in general, relatively speaking. My guess is, chips is the best, ice-cream is the worst, choco is better than sweets. Am I correct?
  5. I have studied some information on web, it's like there is usually a layer of coating applied to the surface of many circuit boards. In that case, how could dust and dirt affect the function of the board? Is it because the coating is an added cost so it doesn't apply to cheap boards? Yes, typo, it's disassemble. Does it practically require significant amount of dust and dirt which is usually due to intention or accident before it is enough to affect the electrical connections?
  6. Someone in an outdoor open area dissembles and repairs an old Television, cars and traffic around, full of dust and dirt and polluted air. Are most circuit boards, electronic components of any kind, manufactured in any generation able to tolerate dust and dirt to some extent by design? Is it just considered and designed to have some protection so that surrounding pollutants cannot make too much damage or is it not particularly designed but it has to be a lot of dust and dirt ( e.g. which are done by accidents or with intention ) before any damage can occur?
  7. From the scientific viewpoint, is it making a real difference? I think any cheap cloth would do the same job, if no debris is stuck when you wipe your delicate screen with your cloth, if there is any, then a cheap one or expensive one would scratch your baby too.
  8. I'm living in a developed country where I have never experienced starve, I may have experienced overweight more often. I know that, I understand that for a balanced diet, one cannot live with fruit and vegetables. Here I have two major questions about this. 1. If I haven't had ANY fruit or vegetables for a few months but I still take in meats and carbohydrates, could I have deficiency in vitamins of any kind? 2. If I practice fasting and do not eat anything at all for a week, and probably drink only distilled water, could I have deficiency in vitamins or other essential materials for life? I'm looking for medical or scientific advice rather than legend or unproved information on the web sites. Thanks.
  9. approx. 200ml 13-14% alcohol by volume every day, does it exceed daily alcohol limit recommended?
  10. Results on Google suggest that the effect is not yet known. Is there any new research or report suggesting other possibilities?
  11. Only differed by frequency, wavelength but they are all fundamentally done by light, is that right? When you put a physical credit card or stored value card near a payment device provided by the merchant, is it using the identical technology as that when you put your mobile phone close to the device and pay with your mobile phone without physical card?
  12. but you don't usually heat the dishware, e.g. dish, knife, spatula, bowl, etc
  13. I mean, fine scratch that you can probably find under light sources and you don't even feel it with your fingers. Are those fine scratches enough to harbor germs and bacteria? I'm not talking about large scratches or cracks that I'll simply toss them without question.
  14. I find that when I cook with oil, if the pan isn't hot enough, the oil runs slowly, but when it gets hot enough, the oil runs faster. How to explain this phenomenon?
  15. It's said latent heat of boiling water or steam will cause more damage. I find that when I cook and the water is boiling, if I put my hand near the steam I wouldn't get as much pain as I accidentally put my hand directly into the boiling water. I would probably hold on a few seconds under the steam but if I put my hand into the boiling water I won't be able to withstand one second. Why is that?
