Never before in human history has it been so easy to get through each day with so little movement -- and it's literally killing us.
Before I tell you about the latest research on this, think about your own day for a minute and how much time you spend sitting.
Many people spend between six and eight hours a day on their rears at work, not to mention an hour or more during their commute and a couple of hours a night in front of the TV.
I know folks who turn the TV on during primetime and don't get up again until Leno says goodnight -- except maybe to get a snack.
It adds up fast... and if that sounds a little too much like your typical day, find a way to work more movement into it -- because a new study out of Australia finds that eight hours of daily sitting will increase your risk of death in the next three years by 15 percent.
More sitting adds up to even more risk, with 11 sedentary hours a day causing the death risk to shoot up by 40 percent, according to the study in the Archives of Internal Medicine.
When you hear about something like this, the temptation is to pull the laundry off the treadmill and start using it again.
But that's not the answer. People who sit all day and exercise at the beginning or end of it tend to have many of the same health risks as those who sit and don't exercise -- and in the new study, they had the same exact death risk.
That means you have to get up, get moving, and take a walk every couple of hours if you can.
If you have a "smart" phone, there are even some apps out there that will remind you to stand and move if you've been sitting too long. Some will also count your daily steps to make sure you're spending enough time on your feet.
Kind of ironic, isn't it? Technology brought us desk jobs and hours of TV, causing us to spend too much time on our bottoms in the first place... and now technology can help us get up and get moving again.
