Nice piece - the science, and the debunking of some myths, continues to evolve.

As an older person, main competition days behind but plenty of quality runs and rides ahead, I feel mentally and physically challenged by these approaches. Ready for the challenges, although wondering whether I let the science take on a higher profile when seeking the emotional wellbeing of being there and doing something to the edge?

Physiology fitting with the psychological elements of how each of us draws energy?

Will keep learning - keep posting - thanks
