Awhile back I found something. A much quoted piece of statistics, that fit, active, fat people are healthier (read "less likely to die") than sedentary, thin people. Later in my reading, I found a refute to that. Someone went back over the study sample & discovered an omission. The Dr. who originally found the correlation
That makes the fit, fat people (like me) who have been patting themselves on the back for doing such a good job of working out regularly, being active, and for once getting one thing right, go "Well, fuck!"
Notice, however, I'm not saying "why bother!". I bother 'cause I feel better, and am a better mother for it. If I didn't get my fat, active ass to the gym every fucking day, I'd never get a shower, I'd never get a chance to stitch, & then every-body's life would be miserable. Trust me.
One of these days I'm going to remember that you can prove anything (including that W is smart) by using Statistics!
