I have been wondering the same.
For the first time in my life, I have 1) not been suffocating all the time, and 2) my body temperature went from 97.4 average lifelong, to NORMAL at 98.6!
I have found that it is very strange to be getting more healthy as I age. I went off wheat, and starting taking a lot of missing minerals. I got better.
On the other hand, my allergies are worse this fall...but that could be the weather...very strange here in California, actually having a little rain!
