they grow no food and raise no livestock. They live without calenders.In fact,they don't count hours,days,or months.The Hadza language doesn't even have words for numbers past three or four. Consequently,they don't celebrate birthdays or anniversaries. Their way of life has changed very little for the last 10,000 years.
To the outside world,this way of living may be hard to understand. We may think that there's nothing the Hadza can teach us.Michael Finkel,a journalist,would disagree. He had the opportunity to spend two weeks with the Hadza and said that being with them changed the way he looked at the world.
