Gary Wolf suggests here that in order to operate effectively in the world you have to know yourself well. I think I know myself pretty well, but I’m not sure I want to know all this about myself. At this stage, I’m not all that interested in tracking every heartbeat, oxygen level, sleep pattern or footstep I take. If I did, I think it would only serve to raise my anxiety levels. I might think I was poised to leave this mortal coil earlier than I anticipate!
But if you do know an app that checks your blood pressure easily, send me the details. My doctor will thank you for it!
