Idea for a Movie

So, I've got this idea for a movie. Its totally at the earliest of stages. But what about this.

It's about a guy, who decides that he doesnt want his family to see him as he becomes elderly, so he decides to say goodbye and start a new life, without anyone, at age 60. So he basically says goodbye, and then begins a new life, from scratch.

Anything there? I dunno. Gonna explore it more I think.
