The Body's "Fountain of Youth" Could Lie In the Brain 118
Zothecula writes "Instead of traipsing through Florida in search of the Fountain of Youth, Spanish explorer Juan Ponce de León might have been better off turning his search inwards. More specifically, he should have turned his attention to a region of the brain called the hypothalamus. At least that's what research carried out on mice by scientists at New York's Albert Einstein College of Medicine of Yeshiva University suggests. They found that the hypothalamus controls many aspects of aging, opening up the potential to slow down the aging process by altering signal pathways within that part of the brain."

A testament to the power of yoga and related mumbo jumbo, Wim Hof [wikipedia.org].
Hof holds twenty world records including a world record for longest ice bath.[1] He broke his previous world record by staying immersed in ice for 1 hour, 13 minutes and 48 seconds at Guinness World Records 2008. The night before, he performed the feat on the Today Show.
Dr. Kenneth Kamler monitored the event to explain the effects of using the Tantric Buddhist practice of Tummo to control one's body temperature. Tummo has been practiced by Yogin monks in Tibet and other areas of the Himalayas.
Wim describes his ability to withstand extreme cold temperatures as being able to "turn his own thermostat up" by using his mind.
In February 2009 Hof reached the top of Mount Kilimanjaro in his shorts within two days.[2]
In 2007 he attempted, but failed (due to a foot injury), to climb Mount Everest wearing nothing but shorts.[3][4] Hof has been criticized for his stated justifications for this attempt: "Edmund Hillary's ascent of Mount Everest was a testament to human achievement; my climb of Mount Everest in my shorts will be a monument to the frivolous, decadent nature of modern society."[5]
In 2009 Hof completed a full marathon (42.195 kilometres (26.219 mi)), above the polar circle in Finland, in temperatures close to 20 C (4 F). Dressed in nothing but shorts, Hof finished in 5 hours and 25 minutes. The challenge was filmed by Firecrackerfilms, who make productions for BBC, Channel 4 and National Geographic.[6]
Hof again broke the ice endurance record in 2010 by standing fully immersed in ice for 1 hour and 44 minutes in Tokyo, Japan.[7]
In 2011 Hof broke the ice endurance record twice, in Inzell in February and in New York in November. The Guinness World Record is now set for 1 hour and 52 minutes and 42 seconds by Hof.[8] On April 18, Hof got the test results regarding the "The influence of concentration/meditation on autonomic nervous system activity and the innate immune response" case study, demonstrating that he is able to directly influence his own Autonomic Nervous System and Immune System. Hof seems to be able to raise his cortisol levels and lower the amount of cytokines (flammatory bodies) just by using his meditation techniques. A different study on Hof while immersed in ice showed that Hof suppressed the cytokines by 100 percent.[9] In September, Hof also ran a full marathon in the Namib Desert without water. The run was performed under the supervision of Dr. Thijs Eijsvogels.
Not mentioned is that he also ran a marathon in 40 degree heat in his fifties without stopping for water.

meditation as a means to control thoughts (Score:4, Interesting)
the next breakthrough would be to work out a categorical and undeniable way to demonstrate what those thought processes *are* that make a difference, i.e. what *kinds* of thoughts result in slowing down of ageing.
the very very unfortunate thing for those people who like to bash religion, meditation *and* science by sitting on one side of the fence or other and slinging mud [cue down-moderation of this post as an example, because i dared to link science and meditation *shock horror*], will be that it will be found that deep restful states of meditation are the way to gain the kind of control over the hypothalamus that is being described, here.
this link between thoughts and "physical effect" really isn't that hard to imagine. examples are as follows:
* "i'm hungry". if you're a dog, you automatically salivate at the sight of food.
* "i'm angry". you release chemicals into your bloodstream, such as adrenaline.
* "i hate you". your body releases chemicals that are similar to SNAKE VENOM. hatred *literally* poisions you.
* "i love you". all sorts of wonderful endorphins released. and a hell of a lot of hormones.
* fulfilment of vengeance (revenge) releases a chemical that *literally* tastes "sweet". hence the phrase "revenge is sweet".
thought. chemicals. thought. chemicals. thought. chemicals. the chain is *really* clear.
why is it therefore so hard for people to understand that control over thoughts can result in significant life-prolonging benefits?
perhaps it is because it's actually quite hard to keep control over our thoughts. or maybe we wish to deny the link, so that it's possible to continue to feel whatever-we-wish-to-feel without considering that there might be consequences [for ourselves]. that would be a *lot* easier, wouldn't it. i'll be interested to see if the "wisdom of crowds" a la "slashdot moderation" as a whole accepts these kinds of words. very interested indeed.
