Gotta get some use of that medical malpractice insurance.

VIOLENTLY DAYDREAMS?

I assure you that I am quite calm. Just trying to make sure that people do not get misinformation after the usage of "technically". And this post is more like the "science side of tumblr"... but on FS.

You are not technically permanently sunburned. You do have higher baseline levels of melanin than Caucasians , but you can still get sunburned. Sunburn involves more than just melanin, such as inflammation and epithelial vasodilation (which is why there is reddening and swelling). Black people are still alive, thus are not walking dead.

I think UVC is short enough wavelength that the atmosphere, particularly the ozone layer, absorbs essentially all of it, making the amount of radiation that reaches the Earth's surface negligible for anything but a very sensitive measuring instrument. I know UVA is lower energy than UVB, but it does penetrate deeper, so is more likely to go through all of the layers of skin and reach the live cells. This can cause basal cell carcinoma or malignant melanoma. The long term exposure, deeper penetration, and usual lack of protection (you have to make sure your sunscreen says specifically that it blocks both UVA and UVB, otherwise it just does UVB) is why UVA is dangerous.

gary17 is right. It is called apoptosis, and ignoring apoptotic signals is one of the hallmarks of cancer.

Except that this was at least two generations ago.

Most people with at least a middle school level of education have heard of Jonas Salk.

Is that just for the Friends intro, or is that supposed to apply to life in general?

Then they should learn how to properly park their vehicles, or spend the extra time correcting their mistakes.

If your truck is bigger than the road lanes, then it should not be legal to drive on the roads.

Mindless drivel with a facade of profundity. Try reading "The Natural Philosophy of Time" by Whitrow.

Well, I guess most students don't give a shit, either. Pass the test, pass the class, forget everything, move to the next course, have to relearn stuff, barely pass, etc. It certainly makes it easy to seem smart without trying at all. At what point does seeming smart become indistinguishable from being smart?

I currently live in Florida. It has happened to me everywhere I have lived, though.

I did that, too. It often is not a difficult feat to accomplish.

Sure, the internet. But, I have definitely encountered plenty of people in real live conversation that will stick to their opinion as fact, even after presenting them with reputable evidence to the contrary.
