Yet another study has been done on sedentary lifestyles and how even a little exercise helps us live longer. What's funny to me is the conclusions they draw.
This one says an hour of TV takes 22 minutes off your life - the equivalent of two cigarettes. Why an hour of TV? Why not an hour of reading a book? I guess they decided that reading a book for an hour offers more benefits; but who are they to decide which hour is bad for me?
I like to watch The Science Channel. Does that not outweigh the 22 minutes lost? What about the time I spent catching up on the day's news or writing this blog?
One conclusion we can draw, however, is that movies are definitely healthier for you than books. It takes several hours to read a book, but a movie with the same story only requires you to be sedentary for about 2 hours.
This is good news for smokers, too. According to the math behind this study, going to a 2 hour movie instaed of reading an 8 hour book saves you 6 hours - meaning you offset 12 cigarettes.
My point is that the math behind these kinds of studies can be used to say just about anything. Here's a final calculation for you. To me, the hour spent exercising is an hour of my life gone. I'd rather lose only 22 minutes while I enjoy an hour of TV or video games... or even a book.
