I’m not a scientist, but I have a simplistic adaption of what has came to me from reading.
Genetics are something we can’t change short term, but time and environment may be able to change what our genes do, and how they react to stuff over years and years of living and our bodies adapting to stuff. The affect of environment may not be able to change some stuff fast, but it can change some things extremely quick.
My definition of environment is the air we breathe, the food and water we ingest, the sounds we hear, the temperature we live in, the stress we feel, and so on and so forth.
I’m not a scientist though, but well, some of this feels like common sense . . .
Well, that’s it for now. Maybe this makes sense enough to some folks to create interest . . .
