For tens of thousands of years, calorie restriction due to food scarcity, exposure to extreme heat and cold, waking with the early morning light, physical labor, connection with nature, face-to-face communication and living in community were inextricable parts of the human experience.

After nearly one hundred years of innovation focused on convenience, humans need to purposefully self-impose these conditions as a means to cultivate wellbeing.
