Four years ago I could eat a gallon of ice cream a week without much of a problem - I have good genes. What changed? Well, I did get older, no stopping that, but more importantly, my scheduled changed. I stepped out of the HR position and moved to the sales floor. Where as back then I rode bicycle, lifted weights, and all sorts of good exercise stuff, now I do so rarely. Back then my schedule was fixed, almost every weekend off. Now is fully flex - on the scheduled which was just published, Monday I'm in at 0900, Tuesday I'm there at 0500, Wednesday I'm in at 0900, Thursday I'm in at 0500, and Saturday I close the store. And the following week it's going to be different. Try getting an exercise routine going with a schedule like that.
I'd originally set February as the date I was going to step out of management... I think I start the talks on Monday. Of course, till everything is said and done, March might actually be the month I step down. I can't wait.
