Is anybody solving really cool problems anymore?
Mz: Efficient weight loss technologyNot a technology, but I have lost several dress sizes as a side effect of working on my health issues, which are supposed to be unresolvable.  And, yes, I feel I am solving Cool Problems`(or, more accurately, I think I am coming up with Cool Solutions).  I have slimmed down without starving myself or even counting calories.  Initially, exercise per se wasn't really a part of it either (though I was more active with having a job than I was when I was bedridden -- I used to joke about my 'get out of bed more often fitness plan' -- still, I didn't "work out").  These days, I do a lot of walking because I live without a car but I do not have a gym membership or otherwise workout.  Yes, I did slim down more with getting rid of my car, but the primary mover is still diet chemistry, supplements and generally working on getting well.Some things I have worked on:
1) Body chemistry.  The typical American diet is too acid.  Excess acidity has a number of negative consequences, including promoting infection.  There is (supposedly) research that indicates that the type of microbes you harbor impacts whether or not you end up obese.  Which brings me to point 2:2) I have actively worked on fostering more good flora in the body and extinguishing bad bugs.  We are all crawling with millions of microbes and cannot even digest our food without them.  But I was, at one time, overrun with multiple antibiotic-resistant infections which were killing me.3) Lifestyle changes that fit with my attempts to control what types of flora inhabit my body and my attempts to keep my body chemistry in a healthy balance.Some nifty things I have found out about using chemistry to heal the body better than modern medicine can:A)I can stop a nosebleed by taking calcium supplements.  Calcium is necessary to start the cascade of chemical processes which leads to clotting. I used to suffer routine nosebleeds/blood seepage from my sinuses.  I rarely do anymore.  If I find I am having an issue with this, I just take some calcium and it goes away.B) Copper is has antimicrobial properties.  Buying a few copper pieces for my home and finding an affordable source for plain old sheet copper in sizes that work for an individual household (as opposed to the quantities that get ordered for industrial purposes) has revolutionized my life in ways I don't know how to begin to explain.C) Infections that most people think you have to live with for life can be cleared from the system using a few herbs and vitamins.D) Gray hair can be reversed (at least to some degree) with the right supplements, which depends in part on why your hair went gray.  I have less gray hair now than I did in my mid-thirties.
