"Genetic predisposition is not destiny." ~ Kranzler.
It's the best excuse human beings ever came up with. I guess the fact that it's often true helps. We use it to explain behavior, illness, addiction, traits, likelihood of success, and even the color of...Whatever. Nature versus Nurture. Genetics. DNA. Heredity and components beyond our control play a large part in determining the appearance, attributes, health and likelihood of whatever in our lives.
Forgive me for oversimplifying a very complex topic. The greatest scientists the world has ever produced can't agree on this one.
Nature versus Nurture. But hey ~ what the heck. I'm gonna give it a shot. It's not my fault. It's the way I am. Simple. It's in my genes.
There are some things we can't control and some we can. But often we fall back on "That's the way I am" or a similar phrase as an excuse to not be something more. Predisposition is not destiny. As human beings we have a lot to say in our choices and our destiny.
Here's a thought ~ Genes have epigenetic markers that serve as a volume control and adjust the intensity of how a gene expresses itself, and over time, the environment, our lifestyle and yes ~ even the decisions we make can alter these markers. Genes determine a lot ~ An awful lot. ~ But Genetic Predisposition Is Not Destiny.
