We begin this week with David telling us about his taking a nostalgic walking jog listening to the music of his youth on his headphones and how the music and the memories inspired a brisk healthy walking jog. We then learn what an NFT is and how it protects unique digital data. Next we discover the technology behind private browsing that can block much of the annoying trackers that we experience when browsing the internet. David details the advantages and disadvantages of each of the three that he has checked out for us. We finish with a discussion of how coupon apps can save us money when checking out at our favorite retail stores.
