Will baby boomers live much longer than expected?
I'm assuming the estimates are roughly good ones, having taken into account all the obvious things. Advancements in medicine and treatment, changes in diet and lifestyle, changes in physical fitness, mental approach (ie "
70 is the new 60"). Overall, I would think the formal estimates are going to be shown to be reasonably good.
It'll be an interesting thing to eval the estimates in about two years, once the age-group impacts of the SARS-CoV-1 virus turn up in the stats and have been analyzed. Stuff like that can take a decent "bite" out of any higher-risk age group. I hope that with the past 20yrs' worth of changes in lifestyle, fitness and diet, that even with "hits" like a global virus it'll turn out that overall age-group lifespan and levels of healthiness improve in such groups.
