67 seems a tad high, no? Babyboomers are generally considered to be those born from 1946-1964. If we assume an even distribution of people born through those years, the average would be 62. However, births per year were higher towards the end of the boom, so in fact I would expect the average age to be even lower.
The average age of the boomers is an spry 67 with a life expectancy of ~85.
