Life span is how long you are capable of living if nothing (heart attack, cancer, car crash, murder) kills you first. Life span varies with genetics, but typically is 110 years for the average human, plus or minus 10 years.
Life expectancy is how long you are likely to live after all possible death factors are accounted for. In the united states it is about 78-85 years for men and women.
Taking the right anti-oxidants at the right time, vitamins, exercise, and other stuff you heard of can extend your life expectancy. Some people overdose, but most benefit, so the average goes up. But doing these can reduce your life span if you do them wrong. They do not increase your lifespan since they don't slow aging, but can reduce it if you wrong, so the average lifespan is reduced.
Despite all the money making fountain of youth claims, anti-oxidants have not been proven to lengthen lifespan, according to 51 scientists who study aging. They can cure some diseases if the right kind are used at the right time, and can hurt you if you use too much at the wrong time, but they don't slow the aging process since your body needs oxidants sometimes and often does not have the extra anti-oxidants in the right place when it needs them. All you can do is have the basic amount, and that is it.
To extend your lifespan, there are two possible ways: 1. calorie restriction that is attained gradually while keeping nutrition above the rda, and 2. Resveratrol.
Both of these can double your remaining youthful years, increasing your lifespan from 110 to 160. This can even increase life expectancy in some ways since your body is better able to fight diseases when it is in a youthful state. However, it can also lower your life expectancy if you don't get enough nutrition, or if you yo yo diet or drop calories faster than 5% per month, or if you take too much resveratrol. The reason you can't tripple your life span by eating even less is there are vitamins we have not discovered yet, and you might not get enough of them if you don't eat enough. My advice is to combine calorie restriction with resveratrol, and get more than the needed vitamins.
