Getting out of bed in the morning is actually a huge privilege.
As an editorial in the latest edition of the Mayo Clinic Proceedings proclaims, sitting is unhealthy. An accompanying research article suggests that the sedentary life may be less unhealthy if one manages to maintain good physical fitness despite the excess chair time, but it's still unhealthy.
While most people are rarely confined to the complete inactivity of bed rest, we are all affected -- incrementally -- by lower levels of physical activity. Ultimately, this has significant implications for how we think about what it means to grow old, and indeed, what "normal" aging really is.
While some progress has been made to reduce tobacco use and alcohol consumption and to promote healthier eating habits, the lack of regular physical activity has not yet been widely recognized as a standalone health threat.
