Genetics factor in for specifics. But do not account for willpower and strength of mind/heart. The weak individual with 'good' genetics is still a weak ass'd derelict. Will still perish to apathy and lazy'ness. While the strong mind/heart will still fight/do till the end.

Well , i have to agree with you .

And the strong minded can still die early to weak genetics. But all in all, i think the strong mind/heart/spirit/whatnot, still trumps the weak mind. i think on this much. Like backpacking with bleeding blisters upon the feet. The pain it fades within a couple short miles. Yet one single broken fingernail, or stubbed toe can totally sideline a weak individual. Force of heart, that is where the power is !!
