Your post led me to run some quick numbers...so I searched the web, and got life expectancy for white males starting in 1930.

I then graphed it and added a trend line.
If you were born in 1930, you should have lived until 1990 (~60 years), but by 1990, the avg life exp was up to ~73, so you gained 13 years. 13 years later, in 2003, it is around 75, so you gain another two years. Obviously diminishing returns, but nevertheless, a gain.
Similarly, for someone born in 2000, the life expectancy was ~75. 75 years later, assuming similar gains to the last century, you live to nearly 100, giving you an additional 25 years to live (in other words, as each generation lives longer, each gains more years) - so you make it to about 100, and you should live to say, 110. So someone born in 2000 should live to 2110 or later. Also, remember that's the average, and people routinely live to 90, and I'm pretty sure things like car accidents lower this average, so if you're reasonably lucky, someone born in the mid 1980's, like me, might well live into the 22nd century, and be the rough equivalent of a 90 year old man. And that's assuming that no huge breakthoughts come down the line from nanotechnology and genetics in the intervening 100years. Note the neat little leap during the 1950s --- which can probably be largely attributed to antibiotics and vaccines for deadly diseases. (i.e. Breakthroughs)
