So, a grizzled veteran soldier in D&D is really only 25 or 30 and not 50 or 60 like IRL.
IMC you're adult at 16, in the sense of 'fully grown' - 13-15 year-olds may well fight in wars, but usually in support roles, squiring and such, and if I need to stat the 15 year old Squire I'd probably make him War-1 (or Apprentice Fighter, but that's a bit fiddly), becoming Ftr-1 at 16. A 30 year old soldier would be considered experienced, 35-40 would be veteran ("old man") age. Many people do live to their '60s though - in ancient Sparta the ruling council had to be age 60+. Few normal folks live past '70s as the slightest cold/flu/injury will likely carry them off.
For active military (Warriors) I use very roughly the following:
Age 16 - Novice - War-1.
Age 21 - Trained - War-2
Age 30 - Experienced - War-3
Age 40 - Veteran - War-4
That's for men who have spent their whole adult lives in military service. Most soldiers retire or die before Age 30, so the War-2 is the typical soldier in most armies. If you conscript the 30 year old farmer into service, IMC he's probably an Expert-2 (with good Fort not Will) as I don't use the Commoner class.
