I have a current supply of 16302 days left to live, maybe. This is an estimate based on my current age (31) and average life expediency. Why would I care to find out or share this number? In 2007 Kevin Kelly, founding executive editor of Wired magazine, wrote a blog post describing his decision and method for tracking the number of estimated days he might have left to live. The concept of tracking my total potential days left greatly resonated with me as I spend a lot of time on self-improvement and learning more effective ways to achieve my goals.
