Some of my buddies have a theory - time in the military does not count towards maturity. So, if you join at age 18 and stay in for 20 years, you're still 18 mentally. Active-duty time does NOT count towards making you older/more mature. (in the Guard/Reserve, you age about half-speed). Also, you'll still wear the same clothes you had from the day you joined. That's why you'll see all the older guys wearing their short shorts and tight t-shirts from the '80s or those ridiculous punk and ghetto-thug outfits. Wanna kill these ads? We can help!
