Let's say you are a hundred pounds overweight, a chain-smoker, and drink a six pack of beer every day after work. You go to the doctor for your annual checkup and are told you have high blood pressure, diabetes, and your lungs and liver are showing damage. Your doctor recommends you go on an immediate diet, quit smoking and drinking, and go on an exercise program. He warns you that there is a real possibility you could die within five years if you do not change your lifestyle. If all things are determined, would this make a difference? Can a man prolong his life by practicing healthy habits? Or is it completely meaningless, when your number is up there is nothing you can do? If all things are determined, wouldn't it make more sense to enjoy whatever you desire as it cannot make a difference?
