Another though day!

A very though day, working from 8 morning to 5 evening, 45 min lunch break and hammering all the day! While I was crushing my samples, I was thinking we haven’t changed so much! Mortars and pestle is being used for 1000 years for grinding materials and still is used! Although we have mobile, car, microwave etc, we still are using many things which were invented 1000 years ago! How about ourselves? Is the way we are thinking has changes so much since 1000 years ago?
