This is a set of two books: "LIFE SHIFT: How We Will Live Longer and What It Means" and "LIFE SHIFT 2: How to Live and Work in an Age of Longevity." While there are no major scratches or stains, there are some minor scratches and stains from use. Please understand that these are used items before purchasing. I am sorry, but I cannot negotiate on the price. Also, I am not considering selling the books separately. If you have any questions, please feel free to comment. Shipping is planned via Yu-Packet Post or Nekopos. *The shipping method may be changed as appropriate. Thank you for your understanding.
