Answer:
An open ended barrel, it is shaped like a hive. It is filled with the flesh, and the flesh is alive!
It regulates our daily movements, but it feels no interest in our lives. It directs us when to come and go, but does not care if we pay attention. What is it?
When I get closer my tail grows longer, but when I go away my tail leads the way.
I do not breathe, but I run and jump. I do not eat, but I swim and stretch. I do not drink, but I sleep and stand. I do not think, but I grow and play. I do not see, but you see me everyday.
A house full, a yard full, a chimney full, no one can get a spoonful.
People take me on walks and I run and have fun. What am I?
