Genetics and my abilities

Okay i understand that i have genes that trace directly to west Africa on my grandfathers side and Cherokee Indian on my great great great grandmothers side but let me get 2 the point okay ive always been told that ive been strong every since i can remember that ive been strong, fast and agile, but i wasn't a big fan of weightlifting even when i did lift weights i got results rather immediately, also im a very fast runner, dint know exactly how fast but ive beat my cousin and he runs track my agility, its something i love the thing is when im running so fast and i see or get in a hasty situation i can get out of it really easy plus i can point out potential things when i run through the woods that i use to my advantage, but i got in a bad health issue in my early teen years and it made me gain a lot of weight well over 230 it effected my speed and agility but increased my strength, but in recent months ive got over those issues but my speed agility and strength has change dramatically i seem to be even stronger, even faster and more agile i wasn't any thing close to this before i gained all that weight now after the results are amazing, but i still have alpha thalessamia (blood deletion) but its only minor so my question is am i like this is it genes or physics or some other source i want straight answers, no bullshit, no criticizing, or insults these Will be highly on no tolerance basis if you do then you will be reported point blank period....

alpha thalassemia is genetic (autosomal recessive)

i find it interesting that you can run fast and very agile though as alpha thalassemia causes a change in the oxygen carrying capacity of hemoglobin

you sound like you have the traits of a hunter gatherer and some of the ancestry of one too, so why shouldn't it be genetic? i'd vote yes
