Many who love numbers like to try and work out the breakdown of the time we spend eating, sleeping, working, etc in an average lifetime.
The American Time Use Survey in 2010 worked out an average day for an American adult included about 8.7 hours of sleep, 5.2 hours doing leisure and sports activities, 3.5 hours work and 1.8 hours doing household activities. The remaining 4.8 hours were spent in a variety of other activities, including eating and drinking, attending school and shopping.
That can't be many people's "average day" but the survey has been analysed further and has a lot more data about the different groups who responded.
Similar articles have been written about other countries and this analysis of what people from the UK do isn't official but gets you thinking. And this article tries to focus on the hours spent working and what that means for your work-life balance.
Quantitative analysis can lead you onto MEtrics – collecting numerical data about you and your day for self discovery. My first thought was the line from The Prisoner TV series: "I am not a number! I am a free man!" but maybe this is just an extension of keeping a diary.
Can we measure our narcissism? Is obsessing about the minutiae of our lives really healthy? Certainly the medical profession uses data analysis for diagnosis and technology now enables us to use these figures more effectively so it can be easier to predict problems before they occur.
Many who collect statistics about themselves want to share their findings and compare with others. quantifiedself.com is a site dedicated to self-tracking and has a very collaborative ethos including online forums and even meet-ups.
British comedian Alex Horne has taken the idea of how we spend our time and devised a show called Seven Years In The Bathroom. Apparently he condenses 80 years of activities into a 60 minute show which can't be easy and hopefully, for his sake, causes some hilarity.
When you look back, do you think you will have spent your time wisely or do you feel you didn't have as much control over it as you might have liked? And what thing do you think you will have spent your time doing that will be different from generations before? (I'm addicted to my smartphone so know I've already spent years of my life on twitter, sending emails, etc.)
