I was discussing this very thing with a friend of mine who is very fit and active. We both...
...have been training in gyms for many years and have seen time and time again the newest miracle supplement, piece of equipment or training diet/regime that promises, well, miracles.
The coconut water thing is the newest "miracle".
Some of these things have stood the test of time, so it isn't all bad, but when I think of the billions of dollars people spend on stuff and most of it is of limited or no value... oy.
The onslaught of advertisers that descended on my Dad as he got on in years, pushing "natural cures" for everything from diabetes to sexual dysfunction to hearing loss was amazing. Newsletters, junk mail, books, tapes, courses, testimonials, etc. It was mind boggling! A couple of times I had to get on the phone and threaten a company with a lawsuit if they didn't stop calling him!
I'm not against natural healing per se, but the snake oil salesman is alive and well and lurking just passed your 50th birthday.
