I went down to the Ontario Science Centre for this exhibit today, and found it fascinating..the exhibit shows real bodies of people who were once living, and in various poses to emphasize different body parts...you'll see everything from skeletons to muscle groups, to actual fetuses of humans who were never born..and in perfect condition thanks to a process called plastination..highly recommended
