How Many Hours of Sleep Do You Really Need? I took a class taught by the Penn PI cited in this article, Dr. David Dinges, called "Human Chronobiology and Sleep". I also worked part-time for a company for which he was a consultant while I was a student. He's brilliant, truly one of the world's top authorities on sleep, with an extremely impressive, 112 page CV: [www.med.upenn.edu] One thing he emphasized in his class that really stood out for me is the inverse relationship between exposure to light (especially short-wave/blue light around 470nm) and melatonin production. If you're exposed to light (i.e. from a TV, computer, phone, etc) right before you try to sleep, melatonin production is inhibited, and it's going to be very difficult to fall asleep. EDIT: If anyone's interested, here's the syllabus for the course I mentioned: [www.sas.upenn.edu]
Jungle Survival: Finding Water" Because jungles are so wet, collecting rainwater is probably the easiest part of survival. Leaves on the rainforest floor are large because of the limited amount of sunlight they get. The larger the leaf, the more of the sun's rays it can soak up. Large leaves are useful in collecting dew and rainwater. If you have a container to store water, simply angle a leaf into it overnight or during a rainstorm and you have some fresh drinking water in no time. You'll fare even better if you can find a running water source. Believe it or not, plastic bottles also work for boiling. Green bamboo has clear and odorless water inside it that you can drink. Another way to collect water is to make a solar still. The moisture from the ground reacts with the heat from the sun to produce condensation on the plastic. These are just a few methods you can use.

Sleepyti.me Calculates the Best Time to Go to Sleep So You Wake Up Refreshed There is no medical/scientific evidence to support the claims that this app will help. First of all, the "90-minute sleep cycle" idea is just that, an idea. Saying that people experience regular, 90-minute cycles is like saying all people have exactly 1.7 children since that is the national average, when, in fact, NOBODY has exactly 1.7 children. Also, sleep stages very by cycle dramatically, so waking up after 4.5 hours is very different from waking up after 7.5 hours. Finally, there is very little evidence to support the claim that waking up at the "end of a cycle" is any different than any other point in the cycle, especially if its a later cycle that consists mostly of REM and Stage 2 sleep. This is the second sleep-related article in the past couple of weeks on this site that has featured inaccurate, misleading information.
universal-edibility-test Getting lost or stranded in the wilderness is serious business, and you need to make sound decisions to give yourself the best chance at survival. It also helps to know some basic wilderness survival skills. To make sure you're safe from the elements, you'll need to know how to build a shelter. To provide you with an opportunity to cook food, boil water and send a rescue signal, you should learn how to build a fire without a match or lighter. But just because you can live without food doesn't mean you should. It's dangerous to eat a plant you're unsure of, especially in a survival scenario. If you're in a survival situation and you don't have a book on local edible plants, there is a test you can perform to give yourself a good shot at eating the right thing.
Ketosis and Athletic Performance: More Than Fat Loss The above video is a presentation by Peter Attia, M.D. His talk is somewhat technical, but I always write blog posts hoping 20,000 people will *love* them, not that 1,000,000 will *like* them. In this presentation, you will learn (in my words, not Pete’s): - More about nutrition than most MDs learn in med school. - How ketosis-adapted performance can aid fat loss and high-altitude resilience. - Why the calorie estimates on treadmills and stationary bikes are complete BS. - The three primary systems of energy production and basic organic chemistry, both of which aid understanding of all athletics. Even if you struggle a little with vocabulary, the first 30 minutes are well worth watching a few times. This talk made me immediately want to jump back on the Cyclical (or “Cyclic”) Ketogenic Diet (CKD), which was conceptually introduced to me in 1996-1998 by the writing of Lyle McDonald, Dr. If you’ve experimented with ketosis, what was your approach and experience?
Make 46 Meals for Under $100 in 4 Hours Tesla unveils a battery to power your home, completely off grid CEO of Tesla Motors, Elon Musk, landed an official message unveiling the Powerwall, a battery designed to power your home. The message came at a convention center powered completely by renewable battery power. The battery unit itself contains the same batteries present in the Tesla electric cars. The 7kWh unit will ship for $3,000, while the 10kWh unit will go for $3,500 (get the big one). They will store electricity from the grid or from solar and wind generators on site and if the grid goes down, they will continue to power your home indefinitely This feature makes them ideal for developing nations that are leap-frogging power grids completely. Musk refers to it as changing the "entire energy infrastructure of the world." The batteries will begin shipping over the summer of 2015 and mount on the wall, looking like this Here is a clip from the initial release Powerwall comes in 10 kWh weekly cycle and 7 kWh daily cycle models.

How to Avoid Sounding Like an Idiot When Discussing Politics Just curious; do you consider attacking the character of a candidate to be an ad hominem? I've been forced to point out on a few occasions lately that right-wing types absolutely love the argument from ignorance fallacy, strawmen, slippery slopes, and - you forgot one, although it's closely related to slippery slope - simple fear-mongering. These all work like a charm on idiots (i.e. Being a lawyer, I sometimes can't resist pointing out that the structure of an argument - prior to even addressing any factual deficiencies or differences in opinion - is simply faulty. I realize my bend is showing, but I'm really not an across-the-board Democrat. I personally know both conservatives and liberals who do that, and I see it on both sides in the public arena as well. If it's personal rather than political, you bet.
