When you nearly kill yourself checking on the effect of a dud 40mm using a potato gun and a wall.
When you you become thoroughly disappointed with yourself for not being able to fire an AK on full auto as well in RL as you can in Inf.
When you decide that it might be neat to re-enact important historical incidents in Inf (Kennedy Assasination, Texas University Sniper, etc. . . . hey, with a good mapper, and some people who like to pay attention to details, it could be done . . . the Texas University Sniper could have some promise, you know? Snipers in the tower versus CQB/Assault specialists that have to INFILTRATE!!!!! the Tower and eliminate them, maybe a few people playing as Civvies, so that the Infiltrators are only successful if at least one civie lives
When you turn purple holding your breath as you attempt to get the crosshairs on your scoped Remington 30-.06 bolt action to stop moving entirely.
When you play Inf so much that you're tendonitis gets too bad to fire an actual gun.
When people HEAR about your little idea to recreate those historical events listed above and begin suspecting that you are "planning something"
You play Inf WAY too much if you forget what an orgasm is.
When you begin to believe that a 40mm or frag grenage exploding under you will leave your body intact.
when you are hospitalized attempting to find out if your K-Bar skillz are as good in RL as they are in Inf.
When shots of battle carnage on the news just aren't realistic enough for you anymore.
when you spend more time playing with your avatar and sig in the forums than actually grooming your real body.
When you actually COMMUNICATE with people in the forums more than you do in RL
When you actually SAY the word fux0red in a conversation.
when you actually know from experience what the gum in MREs are for, even though you were never in the service, and don't personally know anyone who was.
When you start to like the Mexican Rice MRE because someone in the Inf forum recommended it.
When you make the mistake of eating the bean burrito MRE cuz somone said it tasted like cardboard, and you couldn't believe it after eating that tasty mexican rice . . . yech, cardboard
LASTLY when you decide to have implants put in your brain JUST to make your reaction time in Inf faster, at least, as soon as said implants are made a reality.
