Just because you believe it doesn't make it true. Let's not go through this whole thing again...
A kenyan held the 5000m and 10000m world record before the invention of EPO. And yes, a world record holder on EPO is still a naturally talented athlete. We understand that East Africans are predisposed to running success.
That doesn't mean they're predisposed to not doping. Compare the national records before and after the EPO era, and you see the same inhuman drop in performances as other nations. Kenyans are good. Kenyans on EPO are better.
