5th Day - Something Old

On my 5th day on the challenge, the theme was "something old"...

I had a few things in mind on what I should post today. But what do you consider as something "old"?

Could it be a 60 year old man?
Could it be a 15 year old dog but still stands guard?
Can it be a 150 year old house?
Can it be a 500 year old tree?
Is it when something you can't use anymore?
Is it something worn out?
Could it be something that had seen generations?

Stayed home today so I tried to take a picture of what seems to be the "oldest"?

Well, for a billion years old, I guess the moon is. Hahahaha.

But still, I wanted to ask you, what do you consider as something old? Maybe it's a state of mind? :D
