That's for your large answer. Also, how can i know how old any wallet(or address?) Is?

Addresses don't have age. The "old" being talked about here is how long ago that address was first posted by the account on this forum. Whether the address is used or unused does not matter. All posts have a time stamp so you can check to see when the post with the address was made and whether it was edited.
