      Sure, if you're one of these idiots who falls asleep on a beach towel to get a tan (which, honestly, I've always found kind of disgusting looking), you should probably use sunscreen.

      But you certainly don't need sunscreen to cope with the 30 minutes you spend each day walking from your car to the office and back to the car again, and to and from lunch down the street and taking the garbage out when you get home at the end of the day.

      And yeah, I'll repeat that - tans are gross. Darker skin is attractive if it's natural. More pale tones are attractive, if they're natural. But some white chick trying to tan herself into J-Lo is just gross and looks... uncomfortable.

      It's also important to know your genetic predisposition. For example, if you have type I (very fair skin), getting skin cancer eventually at some point in your life is inevitable: all you need is to live long enough and get enough sun. The type of skin cancer you will get from such chronic UVB exposure is most likely a basal cell carcinoma (not fatal) and 30% of these occur on the nose. As another example, if you have the dysplastic nevus syndrome (DN), you'll will have a higher incidence of malignant melanoma. This type of cancer is related more to acute sunburn than chronic exposure and is much more deadly: if you detect them early they are 100% curable, too late and they are 0% curable.

      HDL or LDL is not actually cholesterol. They are what they say they are: lipoproteins. Cholesterol is cholesterol. All living creatures (ok, let's just say vertebrates, I am not very sure here) incorporate cholesterol into their cell walls to make cells waterproof. Because cholesterol is insoluble in water and thus also in blood, it is transported in our blood inside spheric particles composed of fats (lipids) and proteins, the so-called lipoproteins. Lipoproteins are easily dissolved in water because their outside is composed mainly of water-soluble proteins. The inside of the lipoproteins is composed of lipids, and here are room for water-insoluble molecules such as cholesterol. Like submarines, lipoproteins carry cholesterol from one place in the body to another. The main task of HDL is to carry cholesterol from the peripheral tissues, including the artery walls, to the liver. Here it is excreted with the bile, or used for other purposes, for instance as a starting point for the manufacture of important hormones. The LDL submarines mainly transport cholesterol in the opposite direction. They carry it from the liver, where most of our body's cholesterol is produced, to the peripheral tissues, including the vascular walls. When cells need cholesterol, they call for the LDL submarines, which then deliver cholesterol into the interior of the cells. Most of the cholesterol in the blood, between 60 and 80 per cent, is transported by LDL and is called "bad cholesterol". Only 15-20 percent is transported by HDL and called "good" cholesterol. A small part of the circulating cholesterol is transported by other lipoproteins. So you see, bad cholesterol is actually good at something very important. Of course, excess is bad. Bad eating habits stimulate the overproduction of cholesterol, much more then what the body needs. So much more that the HDL cannot "recycle" back to the liver, so the excess gets stuck on the artery walls. So the parent is right, cholesterol IS necessary for the body to function. If you magically got rid of all your LDL "bad cholesterol", you'd be dead.

Plus all the other shit they do in order to meet their quotas.
    I was going to mod you troll or flamebait, because that's clearly the intent of your post, but I thought I'd try to educate fellow /.-ers who may otherwise be swayed by your lies. Especially because you added a couple of tidbits of truth to make your argument sound more convincing.

    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.
