Next week on The Exchange, we begin with author Ben Hewitt and his new book called Saved, a meditation on the meaning of money and the concept of wealth. Next, we look at the charged debate over electricity in New Hampshire. And we explore the spike in heroin use in the state; what doctors, police, and policy makers are doing about it. E-mail us at exchange@nhpr.org and join us all next week for The Exchange every morning live at 9/and again at 8 p m, here on NHPR!
