Replaceable You: Live with Mary Roach on Wednesday

Join a live discussion with Author Mary Roach on her hilarious new book about human body parts and what we do to replace them

Ever wondered about transplanting pig hearts into humans?

Can prosthetic legs be better?

How does one build a new vagina or penis from other human tissue?

Human body parts can become damaged or stop working altogether. Patients, clinicians, and scientists continue to explore the possibilities of transplantation, joint replacements, prostheses, and more.

I'm thrilled to chat tomorrow with the incomparable Mary Roach about her new book Replaceable You: Adventures in Human Anatomy!

I’ve loved her previous work from Stiff (curious about what happens to dead bodies?), Bonk (the nitty gritty science of sex), and Fuzz (did you know people sue wildlife?).

Mary takes us on a journey from failed starts to discovery in replacing human body parts in this hilarious and heartfelt book about the human body.

Join us on September 10 from noon-1 pm Pacific Time on the Substack app.

Mary Roach’s Replaceable You will be released on September 16, 2025.

You can pre-order your copy here.
