I don't know do the genetics play such a huge role... new age and all the crazy fucking stuff happening, people are opening up to the reality and are throwing the old lies like religion and bullshit away and are just plain awere.
The thing is, if you train to run only 10.10 - 10.20 seconds in 100m sprints, you will run that and nothing more.
If you want to do something, but trying to achieve it by thinking "it's not REALLY possible" at the same time, you will lose to yourself.
Everything's possible... you can see how even the media that should be "politically correct" comments that it was the "first WHITE maN", and not just "man"... some people want to make you think we are all very differend and make convincing tricks to say "it is true, look", but then hide the things that proofs we are the same.
