When science "suggests" a foreign body "might not" adversely affect you, common sense "suggests" I might not want to put said stuff inside me. My science teachers whom I still remember and respect from 40 years ago would "suggest" I go back and redo my work and go at the problem from a different angle instead of doing the same thing over again and hope for a different result.
OOOPS, I forgot that maybe the science changed AGAIN.
