Big announcement. Planet Money is publishing a book. And as of today, it is finally available for pre-order at planetmoneybook.com. The book is called Planet Money, a guide to the economic forces that shape your life. It has lots of stories, all that can help you use economics to make life a little richer.

From work and career to retirement in food to dating and family.

And of course, we'll be doing some episodes about the behind-the-scenes things we learned

while reporting and publishing this book. Things like this. Pre-ordering a book helps the author so much more than waiting to buy it.

It sends a signal to the booksellers to stock up, to promote it, to put it on that front table when it does publish.

So help us get some strong pre-order sales. You'll get a free gift and a free month of Planet Money Plus if you aren't already a subscriber.

Go to planetmoneybook.com.

And thank you.

Where should I get these D-A-I-D-D-A-I-D-Rion? Come on, quick, on your feet, D-A-N-W-A-N-W-A-N-E-A-N-G. Angel, I have to admit something to you. Too sloppy, Gary. This is not my real voice. Who sloppy? I am a deep fake. Gosh. Angel, I got you. You got, you got nothing. You got nothing. Oh my gosh. Angel was so

clever. If you had called me, I would have followed for it immediately. I would have been like,
