Sunlight and Body Heat Make Vitamin D Inside Your Skin

Many people don’t get enough vitamin D in their food. They still get enough vitamin D, because ultraviolet radiation creates it—usually.

If you’re as fair-skinned as the average northern European, you only need about 20 minutes per day.  All you have to show is an area of skin about the size of your face.

Without vitamin D from sunlight exposure, lactose assists with the use of calcium. So, cultures with easy access to leafy greens plus sunlight or fish, calcium is taken care of and milk has no advantage. Cultures without access to leafy greens, sunlight or seafood need dairy either as a source of calcium, lactose, or both.  You can read more about it in a previous post.

UV Water Purifiers Are Bullshit

To achieve its claimed ability to remove pathogens, water going into CamelBak’s new UV purifier must first be cleaned by a filter from a rival manufacturer. And that rival product is cheaper. That’s according to CamelBak’s own lab testing. And its not the only water treatment technology that’s incapable of performing as claimed.

Good read!  I have a better understanding now of why I boil water when I’m preparing hummingbird food.

De-Stink Your Shoes with a Homemade UV Light Sanitizing Box

Someone posted a five step Instructables project to use germicidal UV lamps to remove odor from your shoes.  You mount the lamps on something to support them, then stick the lamps in your shoes and crank up the heat. The foil around the box will retain the heat and take care of most of the little nasties crawling around in your shoes.

If the women don’t find you handsome, at least they’ll find you handy… 😉

My cycling shoes have a bigger issue being wet than my running shoes, but that’s because I generally spend more time in the rain while cycling than running.  A trick I learnt was to have newspaper onhand for days like that.  Newspaper, not the glossy stuff like you get on some flyers.  Remove the insole if you can, and stuff the shoe with newspaper.  Check on the shoes every 3-4 hours, applying new/dry newspaper if necessary.  The cost to effectiveness ratio is staggering.  Newspaper is incredibly absorbent, and recyclable.  The local free paper is suddenly being delivered to me, but prior to that I’d grab a stack of free newspaper at the local grocery store on my way out.

Researchers Accidentally Discover How To Turn Off Skin Aging Gene

…in mice.  This could be huge. On the other hand, let’s see the peer reviewed articles. Remember “resveratrol”?

Scientists at the University of B.C. searching for ways to slow the deterioration of blood vessels may have stumbled on to the key to youthful skin.

While exploring the effects of the protein-degrading enzyme Granzyme B on blood vessels during heart attacks, professor David Granville couldn’t help noticing that mice engineered to lack the enzyme had beautiful skin at the end of the experiment, while normal mice showed signs of age.

I believe it’s already known that avoiding sunlight helps prevent this enzyme from being released, and in turn keeps skin looking younger. This is just artificially lowering it even further in an attempt to to create immortal, sunlight-fearing vampires.  But it could really help burn victims…

Usually most aging-preventing discoveries cause cancer. Tumour cells (for solid tumours) normally have defects in extra-cellular matrix related genes (genes in the collagen family are sometimes mutated in advanced gastric cancer) that help the tumour invade and spread through tissues.  For example, the p21 knockout mice that gained almost salamander-like regeneration also gained a high tumor rate. The idea that processes in your body involving the stopping of growth and areas dying off are things that help prevent cancer from forming or growing makes sense…
