The oldest human being in history was 122 years old. Will this record easily be shattered in time? Just how long are humans actually capable of living?

Our advanced medicine does a great job of extending average lifespan, but we haven't had much success in extending *maximum* lifespan. That is to say, we can ward off all kinds of disease, but humans seem to have a biological limit around 100-110, and we really haven't improved it. Go to any graveyard with graves from 200 years ago and you will find people who lived into their 100s. You'll also find a lot who died in their 30s of diseases we don't worry about any more, but the super-old haven't changed.
