I don't think we've discussed the latitude/cholesterol/vitamin D 
connection much.  It's interesting, although it makes me wonder about 
whether serum cholesterol levels correlate well with cholesterol in the 
skin for conversion to D.  I do know that there's a lot of very 
interesting information about vitamin D and how many of us are 
deficient.  For example, 
http://www.newmediaexplorer.org/chris/2006/12/17/statins_and_vitamin_d_deficiency_another_blow.htm.  
This article mentions the connection between certain autoimmune 
diseases, such as RA and MS, and D deficiency.  It has been known for a 
while that the incidence of MS goes up at higher latitudes.  I don't 
know if this is true of RA.
