Okay, thanks for the hope.  I share it!

That life expectancy is actually longer than I expected for the conditions.  But, I guess that means that you'd find a fair number of 50 year  old people in the cities and larger ship communities while those that old would be pretty rare in the tinier villages.  So, the age range I'm probably thinking of... would be between 35 and 45 for a male.  Old enough to be the oldest man in the room in more remote places but young enough that they'd still be considered 'marry-able' in the cities.  Old enough to have well honed skills and young enough to use them well.
