My profession puts me center-stage into the research of thalassemias, sickle cell disease, and malaria, and I can attest that Bill Harzia is largely correct. It's a MB, so he couldn't practically provide enough information to teach you the boundaries of his comment, but then he'd be doing your homework for you, "good doctor", and what fun is that? It's more Letsrunny to reject something out of hand that you know nothing about, don't you think? True to form.
