Labelled by Australian social researcher Mark McCrindle (www.mccrindle.com.au), 'downagers' refers to those Australians aged over 60 for whom age is just a number. They comprise 24% of this demographic and feel and act far younger than their age would suggest. They are the fastest growing segment of the 60+ demographic and they value travel, lifestyle, social connection, and they adapt quite easily to new technology.
"Your parents are real downagers, always on the road and up to date with the latest technology."
