And then what?

A while back I was listening to something or reading something about some US president and it gave me a great idea for a book or a podcast. 

I think the thing I was listening to or reading or whatever mentioned something a former president had done after he was no longer president. I think the guy went back to congress. But it did make me wonder, what about all the other presidents? I think we know a little more about what they do now--Netflix shows, I guess? But what else? 

What did Martin Van Buren do when he left the oval office? (For that matter, anyone know what he did when he was in office? He's not one of the big ones when it comes to US presidents. Sorry, Marty. Although, you could do worse). What has George W. Bush been up to? 

And what about other famous people for that matter? Some just stay famous forever, but what about the ones who don't? I mean, Buzzfeed always has its lists of "here's what happened to this once famous Hollywood star that you haven't thought about for ages." 

So, if you want to be an author, and are looking for an idea, there you go. Run with it! All I ask is that you send me a free signed copy when it is published.
