Average age of those who do rallies?

What is the average age of people who do CC rallies?  Looking at rally next door to where we are, the average age seems to be seventies or older.  Do younger people rally much or are they in the minority?

We are not spring chickens, but if we did decide to do a rally we would prefer people mostly about our age or younger.  No insult to those in seventies as I will be there in several years time.

This just a question and not a go at people who do rallies.
