“We just returned from Sydney where we saw our first grandchild, James, now two weeks old. (I’ll skip all the doting grandparent stuff, but other grandfathers and grandmothers can fill it in for themselves). It’s striking to think that he could easily be around in 2100 and, given plausible advances in medical technology, well beyond that.”
Well, the life expectancy now at birth for a man is eighty, taking us to 2090: projecting on using the basis of the increases for the last 20 years, by the time he reaches 2090 the average age of death will be 107, giving him another 27 years and taking us to 2117: by 2117 it will be 118, another 11 years; by 228 123; by 233 125: by 235 126; so about 127 years old, then. Of course, as a rich bugger’s son he’ll probably do about 5% better than that.
