I believe it's the job. The quest to have this job all year, or for years. Now, to me, I don't understand why you would choose to have this job. The stress, every day. The eternal problems every hour.
People tend to grow older, how they look.
They don't look as happy as often. And this has happened with every guy who has been in. You look at the before, you look at the pre and the post pictures of them. And boy, their hair turns color. They age out.
