Do you think your diet and lifestyle have contributed to your health as a senior?

Did drinking alcohol, smoking, exercise or lack of lead to your current health problems? or the health porblems of those you know your age? My mother is 73 smikes, drinks and is diabetic and could care less. The average age expectancy in my family is mid to late 70's for smokers and drinkers. The others lived to be an average of 84.
