Hi folks. Came across this:- 'Flow' vital for happy, fulfilled life While riding a motorbike doesn't actually get a mention, the state described seems very like what, I guess, most of us feel when riding. "Spending time immersed in effortless concentration and enjoyment, or "flow", is vital for a happy and fulfilled life. But how do you make this happen? There are many circumstances that can make you feel happy, but "flow" is the state of involved enchantment you feel in moments when you are fully absorbed in an activity that has meaning to you." Definitely sounds like a good day bike riding to me.
