Sunday Surgical Scrub: May 1, 2016

“Before each and every case, a surgeon scrubs and disinfects his hands. At the same time, he or she becomes solely focused on the task at hand – preparing to navigate a complex surgical path – and ready to confront any difficulties that lie ahead. Here, on the Sunday Surgical Scrub, I bring you what I’m pondering for the week ahead.”

Task at hand: This week I’m thinking about how we, as humans, interact with our environment. A large study of over 2000 participants found that the average human has an attention span of 8 seconds; contrastingly, this was 12 seconds in 2000 before the smartphone revolution. For comparison, goldfish are believed to have an attention span of 9 seconds. Many will argue that our ability to multitask has improved so these 4 seconds lost may not be as significant. However, if you look at all the neuroscience literature, humans actually don’t have any ability to multitask – you can only focus on one task at a time. Although we are very good at switching between tasks, this significantly decreases our efficiency at completing those tasks. One of my favorite lifehacks to get around this issue is, I put my smartphone on airplane mode when I’m concentrating on a topic – such as right now – to avoid my overwhelming desire to switch tasks and forget that I am not in a fish bowl.

Medicine & Macula: New study shows that 10 minutes on a stationary bike – with just 1 minute of intense exertion – provides the same health benefits of 45 minutes of moderate exercise. Out of time? Here is the workout:

2 minutes warm-up –> 20 second burst –> 2 minute slow peddling –> 20 second burst –> 2 minute slow peddling –> 20 second burst –> 3 minutes cool down
