Hi All,
I generally post things here after they have been discussed at great length but I thought this might interest some who have not heard of it. I initially read about this in Southwestern Medicine Magazine which is a publication from UT Southwestern. This link is from a Johns Hopkins study, I'm not sure who is really the leading research facility but no matter, give it a read.
