Ok, if someone has "bad" genes but has been treated like a king (according to your definition, no vaccines, no makeup, aajonus diet, etc.), would he come to better results than someone with "great" genes but has been "damaged" early in life by "biological weapons"? They have both been dedicated and trained as intensively as they could.
And yes, a child losing his legs can still compete in paralympics etc. Unless you're completely paralyzed, there are still ways to show your athleticism.
