Around here, it isn't an age thing. I have never changed a flat on the road without someone offering help. They have all been younger than I am but I think everybody is younger than I am. I carry two tubes, patch kit, 3 CO2 and a pump. Yes, I have needed all of those on one ride. The most fun is asking the kids who ride the local MUP if they need help. I recently showed two guys how to change a tube and gave them a shopping list of what they should take on a ride. They gave me a warning about a lot of glass up ahead that meant I didn't have to change my own flat.
