I used to have this friend at work who got no exercise and ate whatever struck her fancy. She thought it was a little obsessive of me to work out regularly and eat a fairly healthy diet just because I have a family history of heart disease and osteoporosis. She once remarked, "I just figure whatever is going to happen will happen regardless!" I said that's rather like driving the wrong way down the freeway with your eyes closed and telling yourself that whatever is going to happen will happen. I said I was going to keep trying, thanks.
Do you have health concerns, TQC? Do you address them actively or do you just figure whatever is going to happen will happen and why bother?
