I really liked your comparison of humans to machines. I think you are so right! We work all our lives just so that when we turn 60 we have money to stop working and start relaxing. But, by then we will not have enough energy to do everything we wish that we could have. I think life sounds funny and pointless when you think of it like that. I was also thinking how nice it would be to be like the turtles and not have a worry in the world! I guess that's why vacations are so popular. Everyone is trying to get away from life for a little bit.
