i think basics are the base level pivotal conceptual building blox;
most great finds just a layer or 2 higher than pivotal concepts;
after that whatever mechanic gets too many moving pieces as variables to keep in alignment to target.

For me, climbing had been my passion, exercise, yoga even teacher of how world forces work; i dearly miss it!
.
Just as some martial art student seeks philosophy etc. lessons in 'the knowing' by witnessing same forces of balance in own body;
fighting own self as load etc. until can find the flow of it, and be light; 'relaxed good'
i found in climbing, positioning , fatiguing etc. i gave it all, and it gave it back; and helped forge me.
.
Going to be 60 in 2018, don't seem possible; but someday someone/thing is going to say my ride is over; guess i've had a fair run; hope i maid best of it; have many of ye to thank for it!
.
Some lessons, can only be found at the line between can and can't; and surpassing it; this is where climbing took me to!
