Description from the Web: (excerpt)...It's June 2018. Sally picks up a handheld device and holds it to her finger. With a tiny pinprick, it draws off a fraction of a droplet of blood, makes 2,000 different measurements and sends the data wirelessly to a distant computer for analysis. A few minutes later, Sally gets the results via e-mail, and a copy goes to her physician. All of Sally's organs are fine, and her physician advises her to do another home medical checkup in six months.
