The fact that you were born today means that you will be shielded, either fully or partially, from many of the factors that made the average lifespan 30 years shorter 2 centuries ago, infant mortality included. The lack of these factors would then lead to you "probably" having a 30 year longer lifespan ("probably" in the statistical sense).

You could argue that a more robust statistic like a median would provide a better representation of the expected lifespan less drastically affected by outliers, but calling the 30 year difference in average lifespan "meaningless" is disingenuous at best and could represent a fundamental denial of basic empirical evidence at worst (the latter of which seems more likely to me judging from some of your other replies so far on this subject).
