a genetic variation

what is it 
about genetics 
that makes one frail, short 
another tall and blond  
like dice - each has a chance 
of winning and loosing 
and what is it to know 
this before soon after
years will go by before 
we can divine if it was a win 
or a loss - how fair or 
un - it is safe to say it all comes
 to an end: still to gaze upon a tall 
blond gliding across and to spot a man 
barely able to speak waddle along on his mother's arm 
how life goes on too quietly
