Here's the (brutal) thing about genetics...
It'd be one thing if you could say, "Alright, I got sh*t genes, it's time to stop feeling sorry for myself and get to work fixing this sh*t."
In other words, if you could use your determination and hatred for whatever condition(s) you were dealt to motivate you to fix things.
But, obviously, you can't. There's little to nothing you can do to significantly alter the hand you were dealt at birth. Brutal.
Take, for instance, the 5'-2" guy. Unless that poor mofo has a lifelong dream of becoming a ******* jockey or something, he really got screwed genetically. And there's absolutely nothing he can do to increase his height. He'll always be known as the short dude. ******* brutal.
Or how 'bout the poor grunt who's hung like a raisin. Again, nothing he can do to significantly increase the size of his manhood. Think of the humiliation that dude might have to endure if he tries to paly the game. Brutal.
And, of course, there are many more examples of the BRUTAL cruelness of genetics...
