Is it really? Is Bend a Shangri La-in-the-Cascades where 70-year-olds are mere adolescents and 200-year-olds are common? Well, let's look at the numbers.
Figures on life expectancy specifically for Bend are hard to come by. However, the extremely valuable source city-data.com has a table listing the 10 most common last names of deceased persons in Bend and their ages when they died. Averaging them out yields a life expectancy of 76.3 years.
The average life expectancy for the United States is 78.6 years; the average life expectancy for Oregon is 79 years. Measured against those numbers, Bend doesn't stack up very well -- despite its clean air and vaunted "healthy outdoor lifestyle."
What places do stack up well? The Top
What do those states have in common? Most of them have relatively high levels of education and income. High levels of education and income correlate with access to good medical care, and good medical care indisputably extends life expectancy.
So Bend has no magic elixir for extending life. And if you hope to hit the century mark before you check out, here's my advice: Don't move to Bend -- move to a place where there are good doctors and you can earn enough money to pay them.
