Vision Test

the biggest problem, is a lot of people have never been tested for it. I have read the "most" men are colorblind, and "most" women are not, but I am not sure of the validity of that statement.. Likewise, I have read that people who are colorblind see better in the dark. But who knows for sure, without doing a lot of research.

one in 12 males is red/green colorblind, and only one in 144 females. The gene for colorblindness is on the X chromosome, of which males have only one and females two. This results in the lower percentage for females since all X chromosomes have to carry the colorblindness gene.

I remember reading an article in the scientific section of the newspaper on the subject some time ago, and they found that being colorblind had some advantages too. I think it had something to do with being able to estimate distances more clearly, but it might have been better darkvision as couslee says, at least something that was a big advantage in hunting, when we still lived in caves etc. It was a good explanation for why so many people have genes for colorblindness.

Edit: I found a site with lots of information about colorblindness, it also simulates how people with colorblindness perceive certain colors/contrasts:

One of the Last paragraphs indeed states that colorblind people have better darkvision and would be better at detecting camouflaged objects. It seems you would actually have an advantage when applying for a job in the army as sniper/spotter.

I used to live with a guy who has trouble with certain colours. When cooking mincemeat he'd ask my help in determining if had gone from pink to brown yet (ie is it cooked?)

I'm amazed to learn that you had trouble getting a driving license: Over here the driving authorities know and understand colour blindness. The prospective driver is required to demnstrate that they can distinguish whih traffic light is on and which is off, but otherwise there isn't a problem.

And about style... I think the idea of style is dying out- or at least changing in western culture, as more and more subcultures emerge, each with its own "styles" and fashions.

being better snipers and seeing better at night are of benefit is the service. but, at 17 i had little experience firing a gun. only twice had i shot anything other than a BB gun, and still got small arms expert. Anyone who went to lackland, know you only visit the range once, and are firing an unbalanced weapon (.22 cal barrel on an m16 stock, iirc). and 98/100 @100yrds was good enough for a ribbon. . may have been another reason for the two choices, both put me in a position for long distance fire. one as sniper, the other at enemy aircraft (not close by any means). so who knows. I was not able to pull full term anyway so it is all moot. really

as for the girl at the DMV, she recieved her corrections from her supervisor. It was not a dmv policy, but her own conclusions her comment was based on. the "hassle" for me was having to deal with her lack of tact and education. (she really pissed me off)

I have that trouble with meat also. i learned to not look at the meat, but the juices. if clear, it done. is tinted, it's not. then I always give it a little longer just to be sure. steak tho, I like it mooing when I stick it with a fork. lol

Cooking? We don't need no stinking cooks!

Just eat it raw!

Mix a little Shoyu (Soy Sauce for you Americans) and some WWWWAASSSABBBIIIIII and gimme a cold beer and I am ready for the Super Bowl!!!

Ahi, shrimp, crab, poki, tako, etc, etc. YUM!!!
(if you don't recognize it, don't ask...)

Maybe a raw tourist or two! j/k

You should have seen the bunch of us a couple of years ago on a trip (business) to Portsmouth, Maine during lobster season. We showed them how to eat seafood. I will never forget the looks on their faces. When they lost their appetites, we ate their dinners too!!!

Slick.

Yeah, sushi and sashimi are really good! But the seafood has to be very fresh, or it's not going to be very good.

I don't know about the raw beef and other raw meats, though. I'm scared that if you eat those, you might get parasites.

[Fyron]

Eating raw beef, pork, poultry, and other non-seafood meats (well... not too sure about insects and the like ) is a really bad idea.

The equivalent of sushi for beef is called "steak tartar". (Sometimes spelled "tartare".)
