Sunscreen Not So Good for You?
j-beda writes "Don't like sunscreen? Maybe that tan is good for you. It looks like people are rethinking the common wisdom of avoiding sun exposure...

I'm a vampire, you insensitive clod !
Crivens! I kicked meself in me own heid!
No sun -> little vitamin D production = bad.
Some sun -> vitamin D production = good.
Ridiculous amounts of sun -> high risk for cancer = bad.
I didn't read the article, but most things are OK on modetate doses. Cholesterol, for example, is necessary for the body to function.
Too much of any one thing is seldom a good idea.

Ah, so not only tanning makes you look cool, it saves you from dying? Yet another great reason to give in to peer-pressure! o:)
It seems like you just need to use a modicum of common sense. Too much of anything is bad for you. The less "natural" and more refined a product is the less likely it is to be good for you. It is healthy to get outside and do some exercise every now and then.
All this research seems to contradict itself every few years anyway. I suspect a lot of scientists misuse/misunderstand their own data, either to match their own preconceptions, or to make a headline grabbing story like this one.
In Australia, we have much higher UV levels than you do in the northern hemisphere. Skin cancer is a real concern. I have several friends that have had cancerous growth removed while they were in their twenties. Certainly vitamin D deficiencies can be a problem, however this can easily fixed with very low exposure levels. If you ever visit Australia use sunscrean or become a lobster in 15 minutes.
I live in Queensland, Australia. Thousands of people a years die from skin cancer, in fact we have the highest rate of skin cancer in the world. Only stupid people go out in the sun exposed here. Most people in their 50s or older who spenmt their childhood in the sun before the skin cancer campains of the 70s have had skin cancers cut out.
From personal experience I can also add that the sun in the Northern Hemisphere never seemed as hot or burning as the sun in Australia. I could walk around in the summer sun in Boston and barely get even a touch of colour. In Australia I would be burnt in less than an hour - probably quicker. Sun screen is very important in Australia as is a hat and a shirt.
And finally, this article demonstrates the quest of reporters to beat up each marginal scientific discovery into something that it isn't just to get a good headline. With medical news this invariably creates all sorts of problems. The study found that Vitamin D can be beneficial for treating cancers but said absolutely nothing about the delivery mechanism. Getting your Vitamin D directly from the sun also means you get wonderful melanomas via UVA and UVB radiation. Sure, Vitamin D on its own is fine but the side effects of getting it directly from the sun are pretty severe.
If you bothered to read the article, you would be aware that there are different forms of vitamin D, and that most pills contain a different form than that produced by sunbathing (and also not very much of it).
It also noted that excessive vitamin D from pills can lead to a build-up of calcium in the body (not a good thing), which is not an issue with sunbathing.
Vitamin pills shouldn't be necessary at all - if you need them, then there's something wrong with your diet and/or lifestyle.
...leading scientist say that while drinking four to five glasses of water a day is quite healthy, walking around with the garden hose duct-taped to your mouth may cause serious harm.
If science has taught us anything it's that:
1) Everything in moderation.
2) Research causes cancer in lab-rats.

Ok im a little behind this year so correct me:
Cell Phones: not dangerous
Salmon: ok
Sudan-1: bad
Power lines: definately bad
Condoms: dont have holes
Beef: depends on country
Sunscreen: bad?
Lead piping: ok now?
GM food: border-line
Torture: 'acceptable in some situations'
Violent video games: leads to violent people
Flares: out
Mullets: out
Ironic Mullets: in but slipping

As much as the geek inside of my wants to say I avoid sunlight at all costs, it's actually quite the opposite.
I've struggled with acne/pimples a little more then your average Joe Blow, after spending a lot of money on chemicals and useless washing routines I found the cheapest and easiest solution.
Sunlight, I spend a few (moderate amounts) of time at the beach - and within 1 month of just a few hours per week at the beach, my acne was almost gone.
Even in winter I now try to spend a few hours per month atleast in my salt water pool, it works wonders. I also drag the laptop outside every few days and just spend a few hours in the moderate sunlight so my skin gets some extra special attention.

Unfortunately the article does not disclose the researcher's close dealings with the tanning salon industry. Is the science real? Yes. Does it encourage tanning and irresponsible sun exposure? Yes. Solution: it's better to simply drink vitamin D-fortified milk & OJ.
Let's learn something from Australia, where 1 in 7 people get skin cancer in their lifetimes.
/.ers would do well to look further into the hard science and get past the industry-backed FUD.
Rather than, or in addition to, SPF lotion, wear clothing. This brand is lightweight, well-vented and has titanium dioxide built right into the microfiber. My mom (who is sun sensitive from medication) uses them.
Unnatural, isn't it?
Personally, I don't do anything unnatural to my food. No other animal cooks their food, so I don't cook anything I eat, or eat anything that I didn't pull from the ground or kill with my bare hands.
Also, I eat it without utensils, since no other animal does that, and I don't prepare anything I eat - I just pull whatever I want from the carcass right there. My backyard is starting to stink a lot, since I don't bury anything I kill since animals don't.
It's healthier because animals do it that way.
Mod me down and I will become more powerful than you can possibly imagine!
1) Milk ISN'T good for you, period, [sic]
Actually, it all depends on who you mean by "you," and what your underlying assumptions are about resources, technology, etc. If you are lactose intolerant, then by all means stay away from milk. That doesn't mean you can't have cheese and yogurt, though. It is a well-accepted theory that the lactose tolerance mutation of northern European populations is one of the factors that enabled their success (and by success, I mean they didn't all die out). It is also true that Mongolian tribesmen may not have the resources to eat fresh kale to get their calcium, or to buy soy "milk" from their local organic grocery store. However, goats, sheep, and cows can digest grasses and produce milk with--guess what--calcium! But in fact, it's the casein in milk that supplies the protein, and many vegetarian cultures have relied on dairy products for a large part of their protein consumption.
2) humans weren't supposed to drink another animals milk [sic]
You should be careful when using words like "supposed" because you imply you have some sort of insight into the Way the Universe Should Be. Bullshit. You can't say humans weren't supposed to drink milk anymore than you can say humans weren't meant to jump rope. No other animal does that, either. No other animal writes poetry, or commits suicide, or contemplates philosophy. Just because humans differ from other animals does NOT imply any should or ought, so shut your mouth unless you have some Divine Insight. I would like to point out that other animals may not drink milk after infancy, but they do eat organ meat, entrails, eyeballs, and all sorts of other nutrient-rich animal parts that we tend to discard, these days--including partially digested food in the animal's intestinal tract. Maybe you'd prefer eating tripe to drinking milk?
3) This is ignoring the pitfalls falls of todays production techniques whereby they pump growth hormones into the cows so they produce milk far longer than they are normally capable of. [sic]
This is your single valid point, and it is only valid for milk from a regular dairy. Those same organic grocery stores that sell soy milk also sell milk from cows without all those hormones and (though you didn't mention it) antibiotics. But you're tangling the issues, here. That is an argument for better treatment of dairy cattle, not an argument against milk itself. I have a problem eating hot dogs, these days, but that doesn't make all meat repulsive to me.
Maybe someday it will be proven that milk is the poison you make it out to be. But now, the evidence is far from conclusive, and you obviously don't know your milk history. As it stands, milk was probably responsible for my ancestors' survival, and your burden of proof is pretty high. Oh, and a better grasp of English grammar and spelling might help you be more persuasive, in the future. It would be comical that you have a sentence "Milk ISN'T good for you period," ending in a comma, except that I'm pretty sure you didn't intend that.

Yeah, people need to RTFA:
In late May 1997, Chicago Tribune metro columnist (and "Brenda Starr" writer) Mary Schmich was walking to work along Lake Shore Drive, wondering what she was going to write about that day. It occurred to her that it was near graduation time and she thought she would write a column that read like a commencement address. As she wondered what advice she might offer, she saw a woman sunbathing on the shore of Lake Michigan.
"I hope she's wearing sunscreen," thought Schmich, 45, "because I didn't at that age."
And that's how newspaper columns are born.
A couple of months later, the column became an Internet hoax when a prankster - never identified except as "Culprit Zero" - copied it, labeled it as "Kurt Vonnegut's commencement address at MIT,"
If you don't consume dairy, you'll go insane.
Every vegan I've ever met has been some degree of crazy. The less dairy they were willing to eat the crazier they were. Drink milk, stay sane.
