Like Music To Your Lungs

I have been researching now for almost 3 months for solution to the same issues many people are having out there that my wife and I been experiencing. It seems that there is hope with a simple $40 flute. I am a computer technician and if was not for me having a subscription for a computer magazine, I would not have heard of this story.
Why is it that is so hard to get one? or Why does the FDA has to get involved?

If anyone knows this product will work, please let me know how you got it or I can see if my Doctor can prescribe it.

Thank you so much!

It may take a while for the Lung Flute to be available white or gray market.  

I've been wondering about substitutes.

My car - 16 per second = 960 RPM, but doesn't seem to do much.

If we measure our tires circumference then we should be able to calculate the speed for 16 revolutions per second or 960 per minute.

What would be involved in making a lung flute for non-commercial use (not to be sold)?
