SUP is easy compared to surfing, but still is a different skill set which takes a little while to learn.
I love it because it is all about alternately, relaxing and allowing, then pulsing massive leverage.

All this happens to the tune of heat and gravity moving through water - that is the rhythm we recalibrate to on narrow board.

You'll totally get it instantly.

Like yourself I have tried many ways of eating, I just felt drawn to try this as it is so minimalistic.
Ruminants have 4 stomaches and turn grass and weeds into the most precious organic building blocks that are easily assimilated and in the ideal ratios - so reason goes. I had to try it, now it is what I gravitate back to, no discipline required.

I saw your post, very cool, thanks for dropping in!
