You know you're officially Old:

- when they appoint a new Chief of the Defence Staff (senior officer in the Canadian Forces to you furriners) -- and he's younger than you;

- when you find out that the grey-haired Master Warrant Officer with the chestful of medals joined at age 18 -- a year after you got out of the service;

- when someone brings you a "historical" photograph depicting a soldier wearing a uniform just like the one you wore in recruit school; and

- when you realize that the guy in the next office has never heard a manual typewriter in operation, let alone an entire typing pool in full thrash.
