Re: Safety First
I thought the heart being on the left was a myth?
With most people it's on the left, but one classmate from secondary school was exempted from military service when the medical examination found[0] he was mirrored, with his liver and spleen being on the right as well. Can't remember if he was left-handed, although that would fully make sense, in his case.
[0] of course he, and his GP doctor knew about this, but the army medicos ignored the supplied documentation to that effect.
