Nightvision – Too Late (feat. Long Lost Sun)


Q&A:

curiousgeorge972 asked How does taking Adderall for three nights straight affect you?

I have finals coming up and they’re three days in a row. So my plan was to take an Adderall to stay up all night and then one in the morning to keep me awake. I was going to do this for all three days of my finals. I was curious if anyone else has done this before and how did it affect you?

And got the following answer:

If you mean that you plan to stay up for three days straight without sleep, that would not be a good thing and Adderall will probably not do that anyway. What would probably happen is that you would fall asleep in the middle of an exam. Research does show that the best way to do well on an exam is to get a good night’s sleep the night before.

If you did take the Adderall, some of the effects you might feel could include:

fast, pounding, or uneven heartbeats;
feeling light-headed, fainting;
increased blood pressure (severe headache, blurred vision, trouble concentrating, chest pain, numbness, seizure); or
tremor, restlessness, hallucinations, unusual behavior, or motor tics (muscle twitches).
headache or dizziness;
sleep problems (insomnia);
dry mouth or an unpleasant taste in your mouth;
diarrhea, constipation;
loss of appetite, weight loss.

That was my final Answer. asked What are the diabetes warning signs before being diagnosed by a Doctor?

I get thirsty, in the middle of the night I have to pee and drink more water. Pain in my abdomen right side. Not appendix. Removed long ago. Then pain continues on down right side down to above the pubic bone area. Very painful!

And got the following answer:

Type 1 Diabetes
•Frequent urination
•Unusual thirst
•Extreme hunger
•Unusual weight loss
•Extreme fatigue and Irritability

Type 2 Diabetes*
•Any of the type 1 symptoms
•Frequent infections
•Blurred vision
•Cuts/bruises that are slow to heal
•Tingling/numbness in the hands/feet
•Recurring skin, gum, or bladder infections

But if its that painful I would go and see a doctor anyways!

NingNangNong asked What does it mean when you dream that your teeth fall out?

I dreamt last night that my teeth fell out.
In the dream I could feel that my teeth were all brittle and wobbly and they started to fall out one after the other and it was actually quite scary.

I have heard this is a very common dream.

And got the following answer:

One theory is that dreams about your teeth reflect your anxiety about your appearance and how others perceive you. Sadly, we live in a world where good looks are valued highly and your teeth play an important role in conveying that image. Teeth are used in the game of flirtations, whether it be a dazzling and gleaming smile or affectionate necking. These dreams may stem from a fear of your sexual impotence or the consequences of getting old. Teeth are an important feature of our attractiveness and presentation to others. Everybody worries about how they appear to others. Caring about our appearance is natural and healthy.

Another rationalization for these falling teeth dream may be rooted in your fear of being embarrassed or making a fool of yourself in some specific situation. These dreams are an over-exaggeration of your worries and anxiety.�

Teeth are used to bite, tear, chew and gnaw. In this regard, teeth represent power. And the loss of teeth in your dream may be from a sense of powerlessness. Are you lacking power in some current situation? Perhaps you are having difficulties expressing yourself or getting your point across. You feel frustrated when your voice is not being heard. You may be experiencing feelings of inferiority and a lack of self-confidence in some situation or relationship in your life. This dream is an indication that you need to be more assertive and believe in the value of your own opinion.

In the latest research, it has been shown that women in menopause have frequent dreams about teeth. This may be related to getting older and/or feeling unattractive and less feminine.

Traditionally, it was thought that dreaming that you did not have teeth, represent malnutrition which may be applicable to some dreamers.

Other Perspectives:

A scriptural interpretation for bad or falling teeth indicate that you are putting your faith, trust, and beliefs in what man thinks rather than in the word of God. The bible says that God speaks once, yea twice in a dream or a vision in order to hide pride from us, to keep us back from the pit, to open our ears (spiritually) and to instruct and correct us.

In the Greek culture, when you dream about loose, rotten, or missing teeth, it indicates that a family member or close friend is very sick or even near death.

According to the Chinese, there is a saying that your teeth will fall out if your are telling lies.

It has also been said that if you dream of your teeth falling out, then it symbolizes money. This is based on the old tooth fairy story. If you lose a tooth and leave it under the pillow, a tooth fairy would bring you money.

4 Time Champ asked Why do the Ships not arm themselves while traveling off the coast of Somalia?

Maybe 5 armed guards should be on the ship at all times while in a dangerous area. If ships put up a fight, it will decrease their chances of being hijacked. With night-vision and weapons on hand.

Maybe before a ship enters that area, soldiers or navy from their respected country should board their ship to fight the pirates in the event that a threat happens. Im sure the UN can spare 5 armed military personnel for these ships, just until they are in the safe zone.

How should this be handle in your opinion?

And got the following answer:

.
1) Safety.
If you’re carrying thousands of gallons of oil, liquified petroleum gas, chemicals or other hazardous/explosive material, the LAST thing you need is an errant spark.
.
2) Insurance.
Most insurers for whatever reason – (I’m sure #1 is one) – will not allow it.
.
3) International laws.
Most countries will not allow your ship – and therefore your cargo – entry if you are bearing arms. Ships need to make numerous stops for refueling and replenishments between point of origin and final destination.
.
4) To preclude an arms race.
By some estimates, The Pirates of The Somalians have amassed a literal war chest of $80,000,000.00 U.S. dollars. They can and will buy bigger and better weapons than your civilian merchant mariners.
.
5) Costs.
Up to this point, businesses and insurers have been quietly just paying off pirates (ergo the $80M). With shipboard arms, now desperate pirates will: a) become deadlier and b) start sinking ships. Depending on the cargo, that could be a $100,000,000.00 loss. That’s ONE ship.
.
6) Piracy is a land based scourge.
It originates from land. It is an established doctrine, from centuries of experience, that you can’t eradicate piracy at sea. It’s like swatting individual hornets without dealing with the hornets’ nest. Its eradication will only work from land based solutions, not sea based swashbuckling which, while entertaining as movie plots, have always proven futile as policy.
.
(In Somalia, piracy started ‘accidentally.’ Knowing Somalia is a failed state, international fishing trawlers started poaching in Somali waters, displacing legitimate, lawful Somali fishermen. Frustrated Somali fishermen, with no government (Navy or Coast Guard) to assist them, had to fend off those fishing rustlers themselves. They let out in armed fishing boats to scare away the foreign trespassers. Along the way, they ‘discovered,’ “Hmmm . . . Looks like we can make MORE money doing LESS work by [guess what]”)
.
Cheers, mate!

asked How long would you need to stare into a laser pointer to lose your vision?

Using a 1mW and 5mW laser pointer.

How long would it take to have temporary blindness?
How long would it take to have permanent vision loss?
How long would it take to have permanent blindness?

(No, I’m not planning on doing this. It’s for a school project, but I’d rather not find out by trial and error.)

Thank you in advance for anyone who may be able to help me out.

And got the following answer:

The hazards of laser pointers are limited to the eye. Although with most visible lasers, the largest concern is potential damage to the retina, most laser pointers are not likely to cause permanent retinal damage.

The most likely effects from exposure to viewing the beam from a laser pointer are afterimage, flash blindness and glare. Flash blindness is temporary vision impairment after viewing a bright light. This is similar to looking directly at a flashbulb when having a picture taken. The impairment may last several minutes. At night, when the pupil is most open, the effects would be magnified.

Afterimage is the perception of spots in the field of vision. This can be distracting and annoying, and may last several minutes, although there have been reports of afterimages lasting several days.

Glare is a reduction or complete loss of visibility in the central field of vision while being exposed to the direct or scattered beam. This is similar to viewing oncoming headlights on a dark night. Once the beam is out of the field of vision, the glare ceases. While this does not pose a hazard to the eye, it can cause serious distraction and outrage. Glare can be exacerbated when the beam is reflected from a mirror-like surface.

Several individuals have reported temporary blindness when targeted by a number of laser pointers. This is becoming more prevalent at sporting events. A few individuals complained of afterimages lasting several days.

A high school cheerleader reported being exposed at least three times. After the last episode, she reported first seeing “green”, then experiencing partial vision loss, which lasted for several months. An ophthalmic exam found no retinal damage.

A standard laser pointer is limited to be under 5 mW of light power. The damage threshold for the human eye is about 1 mW. So, since 5 > 1, a laser pointer can damage your vision. However, your eye has some built in safety mechanisms. In particular, you have a reflex to blink and look away when you see a bright light. The time that it would take for a 5 mW laser to do damage is longer than the time it takes to blink. So you would likely blink before any permanent damage was done. That is why laser pointers are considered to be relatively safe: because your blink reflex will save you. However, if you suppress your blink reflex and stare into the laser, it can certainly damage your vision.

The reason laser pointers are not generally more powerful than 5 mW is because above 5 mW, the damage will occur faster than you can blink. So if you ever come across a laser pointer with more than 5 mW, you should be very careful (all laser pointers are labeled with their power).

Green laser pointers are usually infrared lasers that are double to green. However, if you have a cheap (and illegal) one, it may not have an infrared (IR) filter, so some IR light may leak out with the green. That is especially dangerous for two reasons. First, to get 5 mW of green, the laser will need to make more than 5 mW of IR. However, IR light can burn your eye just like visible light, so more than 5 mW of IR can and will do damage to your visions. Second, your blink reflex does not work for IR light because you can’t see it. So you could stare happily into an IR laser without even knowing it until your vision started to decrease. Now a legal green laser will have the filter that removes any left over IR light. So this is only an issue if you buy a cheap laser or if you are disassembling your laser pointer.

Hollywood Vegas asked Is there a natural way to improve bad peripheral vision and night-loss vision?

I’m aware that certain loss of peripheral vision, such as tunnel vision, can’t be treated or reversed but I was curious if there were natural way sto improve or treat bad peripheral vision as well as bad night vision.

And got the following answer:

No, not elderberries – bilberries, very similar to wild blueberries, have been shown to improve night vision. Also any natural source of vitamin A or beta carotene will help with that.

If you have a toxic liver, as most of us do in this polluted world we live in, doing a gentle liver cleanse will improve eye health also. Just buy a l1 oz. liquid extract that contains Milk Thistle Seed (aka Silimarin), possibly Burdock Root or other blood purifying herb, and Dandelion Root to cleanse the kidneys. Take that once a day until all gone (about a month). Then buy a 1 oz. liquid extract of just Milk Thistle Seed and take that once a day until used up. While using these herbs, drink abundant water and consume plenty of fiber to keep the kidneys and bowels moving freely.

As for the tunnel vision, assuming that came on slowly, it’s probably astigmatism and can be improved slightly with eye exercises. If it happened quickly, see your opthamoligist immediately, as it can be caused by a retinal tear and/or stroke.
