Re: David Krummenacker
Krummy's doing a fine job. Let's hope he and some others take it to the next level for the U.S.A.
Re: Malaria, those that carry the sickle cell trait have a slight advantage when it comes to survival in areas where there is a high rate of malarial infection. But they are not immune. Those that carry two genes for sickle cell (one from each parent) generally die at an early age.
Most adults in areas endemic with malaria have usually developed the immune response to keep themselves from getting very sick - but no it doesn't mean they have sickle cell. The story is different with small children, who are at grave risk during their first or second exposure to malaria. There are actually different types of malaria, but I'm generalizing here. I don't know what the problem was with Kipketer that's being discussed. Most of his slight slowdown is due to age, not from malaria.
