"It's all in your genetics" is a crutch that modern medicine has handed down because of their lack of ability to cure much of anything and endless push for pharma sales...I mean if people got healthy how is that good for the economy? Plus it mentally takes away the feeling of power and control over one's health and only helps to spiral people down a road of helplessness and self pity....which is where we come to the modern state of escalating diseases and depression.
So I guess the opposite would be to have a positive outlook on life and believe we can control our health. Take full responsibility for the state of health we are in...and know that actions can be taken when we want to improve it.
I'll take option #2.....as I don't think people really suffer genetically from Restless Leg Syndrome.....
