I can’t because, genetics

There are about 7.7 Billion people on this planet at the moment.  Save for identical twins and doppelgangers, everyone has a unique look to them. Yet we all share 99.9% of the same DNA.

With so much in common, why so many differences in appearance and physical capabilities?

Everyone truly is unique and that .1% variation in DNA can explain some of those differences.  I only use the term "some" because as adults the actions we decide to take on a daily basis for self-care continue to make up the rest of the differences among us.

That’s not to say that some folks don’t actually have physical limitations due to something about them that happened at birth or later in life.  When there isn’t a treatment or procedure available to make some sort of change the focus can shift to living the best life possible and thriving anyways.

Sometimes it can feel like our genetics are working against us, however, by keeping us overweight or preventing us from performing a certain activity.  That even causes people to settle on a particular look and feel of their body based on a self-conceived "limitations".

For example: “I have a slow metabolism”, “I’m a hardgainer’”, “I’m an endomorph.”   

My advice is to not assume anything until you actually consult a medical professional and go through a proper set of tests.  

There are other genetic testing services available today and growing.  However, they may not necessarily be administered or reviewed by medical professionals for further evaluation, a medical diagnosis, or prescribed treatment.

Until you get more scientific confirmations about what’s going on with your body, assume that your body’s unique makeup is perfectly normal until proven otherwise.

Start with the fundamentals.  We all need to be able to relax, drink water, and get some good sleep.

Everyone needs to eat a balanced amount of foods with enough calories, adequate protein, and the right variety of vitamins and minerals.

Finally, our bodies are evolved to move.  That’s not based on opinion, but on many many thousands of years of evolution.

Your DNA already knows what to do to live a long, healthy life.

But it still needs your help to do exactly that.
