To anyone thinking that exercise will fix anything: I've owned a Concept 2 rowing machine since 2005. In that time I've done an average of 100 workouts per year, for a total of over 35 days of rowing. Some workouts were relatively easy 120bpm heart rate; some were at a relatively brutal 160bpm. Concept 2 estimates I've burned just over 600,000 calories, or about 1,000 Big Macs. Could I have eaten 1,000 Big Macs in 19 years? I think so.
