Three Things:

1. Stepping on a slug barefoot is yucky.

2. Just becuase you are having blood drawn at a lab where all they do, all day long, is draw blood, doesn't mean that they will do a good job.

3. More things need to come in a size 7 1/2, because 7 is too small and 8 is too big. Specifically, Lands End water sneakers and Jockey french cut breifs.
