Dry air, nose picking are common conditions that happen to almost everyone if these are considered to be the common causes of nosebleeds in adults. What's the problem of asking many people for reference while at the same time I also saw a doctor and specialist? My nosebleed doesn't happen every day, but it happens once every a few months, without any immediate cause I can think of.

Did you mean nosebleeds in adult are common? or at least, not uncommon? As I said, my nosebleeds happen at random times of a year, so I think dry air shouldn't be a cause. Sometimes I am outside for a whole day in the dry wind but I don't have any nosebleeds, but sometimes when I am indoor I could suddenly have nosebleeds.

As far as I remember, I did not have many nosebleeds when I was a teenager. But since 10 years ago, when I was 24, I first started to have nosebleeds which are usually spontaneous, I cannot remember if my nose was once injuried, but even if it was, it shouldn't be anything serious because I never saw a doctor for nose injury. 5 years ago, I saw a doctor, I was advised to a specialist where some simple checks and treatment were done and for the next five years, I didn't have any nosebleeds until recently, it comes back again. There is no pattern for my nosebleed to happen, it could happen in the spring, summer or winter so dry air shouldn't be a reason. Yes, I like picking my nose but I just do it gently and normally. However, I have asked many adults, none of them said they had any nosebleed after their teenage. A registered nurse from a reputed site told me that if it was an ongoing problem of several years, unlikely anything serious because more severe symptoms should come up soon. Could nosebleed have no cause but it just happens to an adult? But I have really asked probably more than 100 adults and NONE of them told me that they had nosebleeds.

Not really a big question. I am only asking for what kind of paste/oil is advised to be used with a piece of wood with unfinished surface

Yes, I have a piece of unfinished wood that I really care and have to be used frequently. However, I don't know exactly what kind of wood it is, what is recommended to apply (and is it difficult?) that should do it for most different woods?

Some products made of wood are finished with a shiny wax coating that I think it's perfectly fine to wipe them clean by water or other cleansers. But we know that there are also some other products made of wood but they are seen to be without any coating. Is it good or bad to clean such wood products without coating? Could the chemicals slowly get inside the wood can age or wear it faster?

We know that convex lens converge light at a point, Is there any other shapes that could also converge light? What if a convex len has only one side circular while the other end is flattened, when the incident light enters the circular side, what will be the transmitted light?

Am I asking you? I didn't even know you exist, and your "wife and children". That I am asking questions here is none of your business.

But what's the difference between the 99% one and the 100% one? The 100% one is almost double the price of 99% one for the same amount of net weight under the same brand.

I can see that a famous chocolate brand Lindt has released three different rates of chocolate and their prices have quite a big difference. The 100% one is the most expensive, while the 99% one is only a fraction of the price of the 100% one. I can guess that reaching 100% for anything may take more processes so the price is much higher but what is the reason of having pure 100% chocolate? Does it have better taste? What is the difference in terms of the health benefits among the three types of chocolate? Is such pure chocolate only good for health with little or no adverse effect? My common sense is normally any chocolate shouldn't be good for health.

I have been trying to roll my tongue for a long time but I can hardly roll any. Although it is not related to genes, is it unlikely for someone to practise rolling tongue if they are not able to do it on day 1?

Why is it dangerous?

Can isopropyl alcohol alone keep away household pests e.g. cockroach, rats, worms and other pests commonly found indoors? Do they fear alcohol? I don't like using pesticides but I like using 75% alcohol to clean things.

On Google, there are two contradictary answers. One is purely genetic so if you don't inherit some genes you can never roll your tongue no matter what. Another answer is one can learn and practice to roll their tongue even if they are born to be a non-roller. Which one is the fact?

I have been hearing about air pollution, global warming, ice calving, running out of fossil fuels in hundreds of years. In fact, a few hundred years is only a very short time in the hisotry of our earth and humanity. Is the world really doing something practical rather than endless meeting and discussion and putting off things? Just take global warming as an example, is there anything actually done to stop or even reverse the damage?

In other words, is there any objective test to find out the problem or differencce of a patient from blood test, CT scan etc rather than assessment by a list of questions or symptoms that we cannot objectively measure or see e.g. feel nervous, feel sad, feel bad

Hi. In other words, the most probable kind of tetanus shot I received three years ago should be still good today? (i.e. one shot only, no known tetanus vaccine record in their computer, no tetanus vaccine received in the last 10 years before that one) Because I wasn't concerned and I didn't ask about what it was at that time. I have never seen about 30 years on the Google results, unfortunately. So yes there are too many different numbers which are really confusing.

I have just watched an old film produced in 1990. In the film, an undercover agent was given a small portable pocket button by the headquarter, it was claimed that whenever she pressed the button the headquarter would get the signal and found out where she was and would rescue her. However, it was about an ordinary crime. Assume that it wasn't about military, was there such technology in early 1990 in reality? Generally speaking, how was the signal sent? By satellite? How far could it reach at that time? How precise was the location could it detect? I am not looking for very precise data, I am just asking out of curiosity.

I have been searching on Google but the information about tetanus is confusing to me. For example, there are different terms, for example, tetanus shot, tetanus vaccines, tetanus booster, tetanus antitoxin. As for the expiration, there are a large range of results from a month, to 3 years or 5 years or 10 years. As for the doses, there are also different results, 1 shot or 3 shots. Is there any clearer explanation about the prevention of tetanus for adult? Added: About 3 years ago I got a tetanus shot after a deep wound cut by the edge of a metal can. Before that I did not get any tetanus shot for at least a decade and I don't know if I got it when I was a kid or baby. I also don't know what kind of tetanus shot I receive from the clinics, but it was only 1 shot and I left without any revisit. Am I still protected today?

Does it only affect the appearance? Will it leach anything into the drinks?

I have a cup that I like it very much, I'm not sure about its exact composition but it should be made of ceramic. It has been used for a few years but I start to find some stain spot of pale black color in the interior of the cup but they shouldn't be stain from my drinks, they are not removable even with heavy-duty scrubber. I wonder what they are.

Hi all. In a conclusion, white color reflects more visible light while dark color absorbs more lights that include other frequency ranges so it is hotter but most harmful lights are absorbed so that not much reaches our skin. White color reflects most visible lights but there are a lot of other harmful lights are not reflected but reaches our skin Is that right?

If a disc is just stored and kept in a box, sometimes taken out and wiped clean, no accident or damage, is there still any data rot? Is data rot caused by human damage or accident or is it a natural deterioration?

Long time ago I happened to read some articles about CD/DVD rot, I don't remember the details now but the key point was - Data stored on CD/DVD would lose a little bit over time. Is it real? If a CD/DVD disc is kept and stored normally, will there be some data loss after 10 or 20 years?

How do they discharge via air? What molecules will react with them? Will they discharge via ground?
