This is an old video, but it has some interesting points in it:
It is basically saying that you can change your genetics if you change your life, bringing to light people who blame their genetics on their issues.
This means that if you're fat or have heart disease, you can't blame your genetics as easily.
"... making simple changes, you can increase your telomeres, thereby lengthening your telomares, and living longer".
I haven't heard anything about these findings at all, which of course makes sense. Weight loss and the such are such big industries that of course no
one would want to bring fourth these findings.
