> Are there studies that support  to live in Europe?

The point is that if you discuss or do a study on vegetarians you would have
to compare them to a control group and that would be some sort of not
vegetarians. I agree there are many kinds of other diets.  What would your
control group be to do a study that supports living in Europe?

I won't be able to post anything more for the next 10 days as I am going
with husband, grandchild 9 years old, grandchild 7 years old and son 26
(their uncle) to do down hill skiing in Åre in the north of Sweden where it
is lots of snow, mild, light, sunny and.....
I'll miss you all!
