Make progress without much effort
Cycling and sailing are the only sports I can think of where you can coast. Just drift. Cruise and relax with the air.
Of course sailing requires the wind and cycling requires the level of the path ahead, but you can pause and relax and contemplate the present.
My life has been a series of coasting. I've been lucky to be able to survive school, walk into a job, impress the workforce with ideas, be a caretaker for two women and a mother, and still have fun.
The rest is downhill from here.
Hope I die before I get old.
