End of Absence

On this episode, Michael Harris discusses the impact of the ‘end of absence’ and what constant connectedness means for the well being of future generations. He’ll also tell us how we can mitigate the effects of technology and preserve the benefits of periodic absence while still maintaining our social connections.

Keep connected… ;)
