Name three things that you can do when you are old...

That was a question on Jaden's homework tonight. His answers left some questions.
1- Drive ( a really good answer)
2- Buy ("Buy what?" I asked. "I don't know, stuff" he answered)
3- Go to the Woods. ("Really, Jaden? Why would you put that? -"Well that is something that you only want to do when you are old.")
