I am 54 and have only ever had a real tree!
We put ours up last Sunday! We take it down a few days after Christmas. Our trees barely loose a needle, so its never a problem to have it up for so long. The key is, we have a fresh cut tree. Our friends have a small Christmas Tree lot. They don't sell them, just grow them for themselves and a few friends. We are so lucky!! We pick one out, and they cut it down and deliver it to us.
Now, if we bought one pre-cut, there is no way we could have it up so long!
