Yes - that's exactly it. You might look around your abode and notice that a tree that used to be a skinny little sapling is now 40 feet tall and 4 feet in diameter. Or you see a photo of your front yard and there were no plants in it, and now it's a jungle with many tall trees... Or you see pictures of all the pets who have passed away. Or you start losing your older relatives. Or your favorite shirt suddenly falls apart and it seems like you just got it. Or your car rusts to bits before your eyes but it seems like you got it last week. I also still get carded (but then, they card everyone).
