It's true that the oldest verified person lived to 122 years - many of those years lived before antibiotics, before smoking was widely known to be unhealthy, before organ transplants, before widespread use of vaccines. The people on the lists of 'oldest living people' grew up in a significantly tougher world and thus many of their peers probably died young from entirely preventable or curable diseases. If those people had lived with today's medical technology and knowledge available to them for their whole lives, that list of people living to 110 would be much longer and undoubtedly you'd see an increase in the number of people giving to 120 and probably to 130.
