Tight lacing

I have bought myself a book for the summer holyday. The Corset, A Culturel History. by Valerie Steele.
Just skimming it I found out that there are women today who wear tight laced corsets everyday in order to get as small a waist line as possible. (That must be considered as body-modification a long the line with scaring and `growing´ horns and beyound my comprehension).

But the interesting thing with this, is that the actual health damage from extreem tight lacing can be recorded and compared with doctors journals from the Victorian time, and perhaps corsets were not as deadly as presumed.
